*DECK LIBRSC
SUBROUTINE LIBRSC(MAXTRA,IPLIB,LBIN,NGRP,NBISO,ISONAM,MASKI,LSHI,
1 NFS,IMPX,IALTER)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Compute the correlation information between a pair of resonant
* isotopes for the resonance spectrum expansion (RSE) method.
*

*Author(s): A. Hebert
*
*Parameters: input
* MAXTRA maximum number of energy bins of size DELI.
* IPLIB pointer to the lattice microscopic cross section library
* (L_LIBRARY signature).
* ISOT index of the isotope been processed.
* LBIN number of fine energy groups.
* NGRP number of coarse energy groups.
* NBISO number of isotopes present in the calculation domain.
* ISONAM alias name of isotopes.
* MASKI isotope masks (isotope with index I is process if
* MASKI(I)=.true.).
* LSHI resonant region number associated with each isotope.
* NFS number of fine energy groups in each coarse energy group.
* IMPX print flag (equal to zero for no print).
* IALTER type of approximation (=0: use exponentials; =1: use Taylor
* expansions).
