Obscure fakeit problem

Craig spotted that when faking a background file with Gaussian errors I failed to correct the VARBKG array for the ratio of BACKSCALE keywords. This meant that the STAT_ERR column would be wrong if the source and background files had different values of BACKSCALE. Fortunately, this is unlikely to have occurred because Gaussian errors are only used with non-imaging detectors. Fixed as bug 11.3.1s.

Updated on Jan 7, 2005 to fix a typo in the original file.

Keywords: xspec
