MODULE: ccdred.ccdproc
SYSTEM: V2.9(?) V2.10.1
NUMBER:	181
MODULE:	ccdred.ccdproc
SYSTEM:	V2.9(?) V2.10.1

FROM:	valdes

BUG:	When using STF images with a flat field that has been processed but
	has lost the CCDMEAN keyword CCDPROC will produce an error of the
	form:

	    ERROR: OPEN: File does not exist (tmp4294ha.hhd)

	A flat field in this state would most likely be produced by
	FLATCOMBINE with preprocessing before combining selected.  The
	combined flat field will lack the CCDMEAN keyword.

	The workarounds are to either use OIF images or add the CCDMEAN
	keyword manually.  This would be done by using IMSTAT to compute
	the mean and adding the CCDMEAN keyword with that value using
	HEDIT.

STATUS:	The error is ignored by CCDPROC in V2.10.2.  The reason for the
	error when calling imunmap with an image which has been created
	but for which no pixel data has been written is under investigation.

MODULE:	immatch.geotran
SYSTEM:	V2.11

BUG:	Geotran was not decoding the transforms list correctly in the
	case that the number of images > 1 and the number of transforms
	is 1. In that situation geotran is supposed to use the same
	transform for all the input images. Instead it was complaining
	about not being able to find the transform for the second image.

	This bug was introduced when geotran was modified to use the
	image template expansion code to manage the transform list
	(part of supporting the mosaic image name syntax) instead of the
	file template expansion code.

STATUS:	Fixed for the next release of IRAF. The workaround is to create
	a transform list with one entry for each image, even if the entries
	are the same.
