Given for shell indices, this will cause the integral buffer to be filled in.

Implements sc::TwoBodyDerivInt.

int sc::TwoBodyDerivIntCCA::log2_shell_bound | ( | int | ,
|  | int | ,
|  | int | ,
|  | int |  |
| ) |  |  | `[virtual]`

Return log base 2 of the maximum magnitude of any integral in a shell block.

An index of -1 for any argument indicates any shell.

Implements sc::TwoBodyDerivInt.
