                 multi_bav(gav)

         returns bin boundaries for the bin centers gav.
         The bin boundaries are taken at the geometric means between
         consecutive gav(i), with the endpoints extended slightly beyond
         the endpoints of gav.

multi_bins |
                 multi_bins(mf)

         The MF parameter is an array of MultiFiles, each created by multif.
         Automatically generates the bin structure which will be used by
         multi_streak (if the GB keyword is not specified).

multi_gb |
                 multi_gb, multi_gav, multi_gexist

         are the default names of the group boundary, group center, and group
         existence arrays in post-processing files.  By default, they are
         "gb", "gav", and "gexist".  If neither is present, drat_gb and
         drat_gav will also be tried.
         If present, gb is the photon bin boundary array, and gexist (if
         present) has one fewer element and is non-zero in bins which exist.
         Otherwise, gav is the photon energy array, and gexist (if present)
         has one fewer element and is zero between elements of gav which are
         not connected.  Isolated points in gav are removed entirely.
         Either gb or gav must be strictly increasing, and has units of
         photon energy.

multi_line |
                 gb= multi_line(nbins, hnu0, dhnu, dhnu_min)

         returns 2*NBINS+1 bin boundary energies for 2*NBINS bins
         cenetered around a spectral line at HNU0 of width DHNU.  The
         result begins at HNU0-DHNU and ends at HNU0+DHNU.  The finest
         two bins (nearest HNU0) has width DHNU_MIN, and the remaining
         bins have equal ratio widths as you move away from HNU0.

multi_memory |
                 multi_memory

         amount of memory used to determine size of spectral chunks.
         Default is 2000000, which keeps the memory required per chunk
         to under a few megabytes.

multi_no_dups |
                 xnd= multi_no_dups(x)

         returns its input vector X with any duplicate values removed.
         X must be non-decreasing and of length at least two.

    interpreted function, defined at i/multi.i   line 1253
multi_opac |
                 multi_opac, multi_emiss, multi_srcf

         are the default names of the opacity, emissivity, and source function
         arrays in post-processing files.  By default, they are "opac",
         "emiss", and "srcf", respectively.  If none of these are present,
         drat_akap and drat_ekap will also be tried for the opacity and
         source function, respectively.  If emissivity is present, source
         function will be ignored.
         The units of opacity are inverse length, of emissivity power per
         photon energy per sterradian per volume, and source function
         power per photon energy per sterradian per area.

multi_streak |
                 result= multi_streak(mf, rays, slimits, gb=common_bins)

         like the streak function, but allows opacity to be built up from
         "slave files", in addition to the "master file" MF(1).  The MF
         parameter is an array of MultiFiles, each created by multif.
         The master file MF(1) contains the mesh, and the master list of dump
         times.  Only dump times which are present in this master list, and
         in every slave file, will be processed.
         The master file MF(1) need not contain any opacity or emissivity data
         at all; each of the slave files MF(2:0) must contain data for at
         least one zone.
         The emissivities and opacities from each file are interpolated onto
         a common group structure.  This common group structure can be
         provided via the GB keyword to multi_streak.  If it is not provided,
         GB is computed by examining the group boundary (or center) arrays
         from the master and every slave file, and building a group structure
         which is at least as fine as every component group structure, at every
         point in the spectrum.
         Example:
           File family "prob_p00" contains the mesh and opacities and
           emissivities for all zones.  Family "pp_h00" contains post
           processed opacities and emissivities on a much finer spectral
           mesh, but only for zones in regions 1 and 2 of the original
           problem.  You want to transport the emission from the
           inner regions 1 and 2 through the overlying material:
             restore, openb("prob_p00"), ireg;
    	 master= multif("prob_p00", zoneuse=where(ireg>2));
    	 slave= multif("pp_h00", zonelist=where(ireg==1|ireg==2));
    	 rays= ...
    	 slimits= ...
    	 drat_start= ...
    	 drat_stop= ...
    	 result= multi_streak([master,slave], rays, slimits);
    	 multic, master;
    	 multic, slave;

multi_streak_save |
                 multi_streak_save, outname, mf, rays, slimits, gb=common_bins

              or multi_streak_save, outfile, mf, rays, slimits, gb=common_bins

         like the streak function, but allows opacity to be built up from
         "slave files", in addition to the "master file" MF(1) and
         saves the streak in a PDB history file.  The MF parameter
         is an array of MultiFiles, each created by multif.
         The master file MF(1) contains the mesh, and the master list of dump
         times.  Only dump times which are present in this master list, and
         in every slave file, will be processed.
         The master file MF(1) need not contain any opacity or emissivity data
         at all; each of the slave files MF(2:0) must contain data for at
         least one zone.
         If the first argument is OUTFILE, a file variable instead of a
         file name, then that file is used for output.  You can create
         OUTFILE and add static variables to it with save (but do NOT call
         add_record) which streak_save otherwise wouldn't know about.
         The output file has history records at the same times as the
         input file.  Each record contains "time" (a double scalar),
         and the two arrays "transp", the transparency (between 0 and 1),
         and "selfem", the self emission (which has the same units as
         ekap in the file F).  The dimensions of transp and selfem
         are ngroup-by-2-by-nrays (where nrays represents zero or more
         dimensions, copied from the RAYS input array).  The RAYS and
         SLIMITS inputs are placed into the output file as non-record
         variables, and any variables in the drat_static option are
         copied form F to the output file.  The gb and gav variables
         are copied from F into the output file as well.  If the drat_glist
         option is present, that is stored in the output file also.
         The emissivities and opacities from each file are interpolated onto
         a common group structure.  This common group structure can be
         provided via the GB keyword to multi_streak.  If it is not provided,
         GB is computed by examining the group boundary (or center) arrays
         from the master and every slave file, and building a group structure
         which is at least as fine as every component group structure, at every
         point in the spectrum.
         Example:
           File family "prob_p00" contains the mesh and opacities and
           emissivities for all zones.  Family "pp_h00" contains post

           mesh, but only for zones in regions 1 and 2 of the original
           problem.  File "prob_strk" contains the streak history.
           You want to transport the emission from the
           inner regions 1 and 2 through the overlying material:
             restore, openb("prob_p00"), ireg;
    	 master= multif("prob_p00", zoneuse=where(ireg>2));
    	 slave= multif("pp_h00", zonelist=where(ireg==1|ireg==2));

multi_times |
                 times= multi_times(mf)

         returns the list of times which will be used by multi_streak.  This
         is the subset of streak_times(mf(1)) which occur in all of the slave
         files.  The drat_start and drat_stop times work as usual.

multi_zonelist |
                 multi_zonelist

         is the default name of the variable which is a list of 1-origin
         zone indices in the mesh of the master file.

multic |
                 multic, mf
              or multic, [mf1, mf2, mf3, ...]

         closes a MultiFile created with multif.
         Presented with an array of multifiles, closes them all.

    interpreted function, defined at i/multi.i   line 217
SEE ALSO: | multio, multif
multif |
                 multif(mf)

         returns an ordinary file pointer for the MultiFile MF.
         Do not use close to close this pointer; just set it to [] when
         you are done.  Use multic to properly close the MF.

    interpreted function, defined at i/multi.i   line 240
SEE ALSO: | multio, multic
multio |
                 mf= multio(filename)
              or mf= multio(file)

         opens file FILENAME for use with the multi_streak function.
         The file MUST be subsequently closed using multic, since
         this function produces a hidden reference to the file.  The function
         multif can be used to return an ordinary file pointer, given the
         returned MF structure.  If the argument is already a stream FILE,
         that file will be used.  The call still produces a hidden copy of
         FILE, so you may set your copy of the FILE variable to [], but do
         not close the file.
         The following keywords can be used to allow for variations in the
         variable names or units, and to specify the correspondence between
         the zones in this file, and the zones in the master file:
         zonelist=index_list
         -or- zonelist=zonelist_name
           is an index list into the (rt,zt) mesh arrays of the master file.
           If ireg is the region number array (having the same dimensions as
           rt or zt, and with its first row and column all 0), and if FILENAME
           contains opacity data only for zones with region numbers 1 and 2,
           you could open the file using:
              mf= multio(filename, zonelist=where(ireg==1 | ireg==2))
           The zonelist should be nil only if the spatial dimensions of the
           opacity and emissivity in this file exactly match those of rt or
           zt in the master file.
           If zonelist is a string, it replaces the default name for the
           zonelist variable stored in the file (see multi_zonelist).
         zoneuse=index_list
           The zonelist specifies how the zones in this file correspond
           with those in the master file.  The zoneuse list allows you
           to specify that only some of the zones actually present in the
           opacity and emissivity arrays of this file are to contribute
           to the total.  This might be necessary to avoid double counting
           in a region covered by more than one file.  Hence zoneuse is
           a list of indices into the spatial dimension(s) of the opacity
           and emissivity arrays in this file.  If nil, all zones in this
           file will contribute.  If present, and if zonelist is supplied
           as an array (rather than out of the file), zonelist should
           have the same length as zoneuse.
           As a special case, if zoneuse is a scalar 0, no opacity or
           emissivity will come from this file; this makes sense only if
           this is the master file.
         opac=oname, emiss=ename, srcf=sname
           specify non-default names for the opacity, emissivity, and
           osource function arrays.  The defaults are given by the global
           variables mutli_opac, multi_emiss, and multi_srcf (see help).
           If the emissivity array is present in the file, it is preferred
           to the source function array, which will then be ignored.
         oscale=opacity_unit, escale=emissivity_unit
           are optional conversion factors to bring the units of the
           opac and emiss (or srcf) arrays into agreement among the various
           files which are to be used in a single run.  The default value
           is 1.0 (i.e.- all files are expected to have the same units).
         gb=gbname, gav=gavname, gexist=gexistname
         -or- gexist=group_existence_map
           specify non-default names for the group boundary, group energy,
           and group existence arrays.  The defaults are given by the global
           variables mutli_gb, multi_gav, and multi_gexist (see help).
           If the group boundary array is present in the file, it is preferred
           to the group energy array, which will then be ignored.  The file
           should specify group boundaries if its opacity and emissivity are
           averaged over finite width bins; group energies if its opacity
           and emissivity are computed at points.  The group existence map,
           if present, allows several disjoint spectral regions to exist in
           a single file.  If the data type of gexist is not "string", it
           should be an array of length one less than gb, if gb is present,
           or gav, otherwise.  By this means you can ignore spectral regions
           which are present in the file.
         gscale=photon_energy_unit
           is an optional conversion factor to bring the units of the
           gb (or gav) arrays into agreement among the various files
           which are to be used in a single run.  The default value
           is 1.0 (i.e.- all files are expected to have the same units).
         tscale=time_unit
           is an optional conversion factor to bring the units of the
           time into agreement among the various files which are to be used
           in a single run.  The default value is 1.0 (i.e.- all files are
           expected to have the same units).
         noextrap=1
           if present and non-zero prevents the opacity and emissivity
           data from this file from being extrapolated as 1/hnu^3 in
           master bins at energies above the highest energy bin in this
           file.
         freqfirst=0
           if present and non-zero means the frequency index is first
           for the opacity and emissivity arrays, instead of the
           default of frequency index last.
