NUMBER: 246 MODULE: images.imcombine, ccdred.combine, onedspec$scombine SYSTEM: V2.10.2 DATE: Mon Jun 6 17:03:15 MST 1994 FROM: valdes BUG: In rare circumstances when using one of the clipping algorithms nkeep > 0 the task will not complete because it has entered a nonterminating loop. This occurs when too many pixels are rejected and two or more rejected pixels have equal residuals the equal residual points are added back. However this is done within the iterative loop and after adding back the pixels the task finds there are now more than nkeep pixels and so repeats the loop with the same result. The work around is to change nkeep. A change is likely to fix the specific case. A value of zero for nkeep will avoid the problem entirely but with the possibility of rejecting all pixels. STATUS: The adding back of pixels should be done outside the iterative loop and this change has been made for the next release (V2.11).
