*
*Purpose:
* Compute self-shielded microscopic cross sections.

*Author(s): A. Hebert
*
*Parameters: input
* MAXNOR maximum order of the probability tables (PT).
* IPLI0 pointer to the internal microscopic cross section library
* builded by the self-shielding module.
* IGRP energy group under consideration.
* NGRP number of energy groups.
* ISMIN minimum secondary group corresponding to group IGRP.
* ISMAX maximum secondary group corresponding to group IGRP.
* NIRES exact number of resonant isotopes.
* NBNRS number of correlated fuel regions.
* NL number of Legendre orders required in the calculation
* (NL=1 or higher).
* NED number of extra vector edits.
* NDEL number of delayed neutron precursor groups.
* NOR exact order of the probability table.
* IPPT1 pointer to LCM directory of each resonant isotope.
* IPPT2 information related to each resonant isotope:
* IPPT2(:,1) index of a resonant region (used with infinite
* dilution case);
* IPPT2(:,2:4) alias name of resonant isotope;
* IPPT2(:,5) number of delayed neutron groups.
* GOLD Goldstein-Cohen parameters. Set to -999. to enable the Ribon
* extended method for a specific isotope.
* MAXXS number of x-s types.
* ISUBG type of self-shielding model (=1 use physical probability
* tables; =4 use Ribon extended method).
*
*Parameters: output
* PHGAR averaged flux.
* STGAR averaged microscopic total xs in resonant region.
* SFGAR averaged nu*microscopic fission xs in resonant region.
* SSGAR averaged microscopic scattering xs in resonant region.
* S0GAR averaged microscopic transfer scattering xs in resonant
* region for primary neutrons in current group.
* SAGAR averaged microscopic self-shielded additional xs.
* SDGAR microscopic self-shielded delayed nu-sigf xs.
* SWGAR averaged microscopic secondary slowing-down cross sections
* (ISUBG=4).
