NAME:
	READ_HXRS_4_SPEX

 PURPOSE:
       Based on settings, calls read_hxrs_fits to get parameters of interest.
		Used as an interface to Spex.

	READ_HXRS_FITS [3], checkvar [2], edge_products
 INPUTS:
	Through keywords so you don't have to remember the input order.

 NAME:
	READ_HXRS_FITS

 PURPOSE:
       Reads hxrs fits files into idl, then
       computes counts/sec and live times for shielded and non-shielded
       detectors and effective total livetime for sum of both s. and ns.
