NUMBER:	314
MODULE:	apphot centering routines
SYSTEM:	V2.10.2 and earlier

FROM:	davis

BUG:	A bug in the centering algorithms thresholding code resulted in the
	cthreshold parameter being interpreted as the threshold in counts
	above (below) which pixels were used for centering rather than
	the threshold in counts above (below) the local data minimum
	(maximum). The problem occurred because the local data minimum
	maximum was being computed but not entered into the appropriate
	data structure.

STATUS:	This bug is not a problem for 2.10.3 and later versions of apphot
	or for the version of apphot in digiphotx.
