# The `PreMonitor_nD` Component

This component is a PreMonitor that is to be used with one Monitor_nD, in order to record some neutron parameters

## Identification

- Author: Emmanuel Farhi
- Origin: ILL (France)
- Date: 01st Feb 2001.
- Version: 0.1

## Description

    Neutron parameters are stored when passing in the PreMonitor.
    If this neutron then reaches the associated Monitor_nD, this latter component
    will measure the previously stored parameters. This enables to study
    correlations between a given parameter in one place of the instrument
    and an other position in the instrument.

    EXAMPLES:
    Here follows a Phase-Space diagram detector (used for guides for instance)

     MyPreMonitor = PreMonitor_nD(
      comp = MyMonitor)

    (... for instance a Guide ...)

    MyMonitor = Monitor_nD(
      xmin = -0.1, xmax = 0.1,
      ymin = -0.1, ymax = 0.1,
      options = "hdiv x, auto, use premonitor");

## Input parameters

Parameters in boldface are required; the others are optional.
