NUMBER: 386 MODULE: immatch.linmatch SYSTEM: V2.11 DATE: Mon Dec 15 12:24:52 MST 1997 FROM: davis BUG: Linmatch could crash with a floating operand error if the bscale scaling algorithm was one of 'mean', 'median', or 'mode', and the reference image contained one or more regions with a zero-valued mean, median, or mode. The error was in the computation of the error in the bscale value. STATUS: Fixed for the next release of iraf. The only work around is to choose the regions used for scaling carefully.
