MIPS Campaign D2 Anomalies
==========================
1. 1st SUR DCE Slope Anomaly
   Status: Closed (pending fix to FSW)
   Description: For the first DCE commanded by each exposure sequence 
	(single execution of CEMIPSUR), the slope produced by the
	on-board SUR algorithm is systematically 9% lower than slopes
	fit to comparable RAW mode data. This effect was seen (at an
	even worse level) in ground testing. For other DCEs, the SUR
	algorithm produces slopes for unsaturated pixels which are
	within 1% of slopes derived by linear, least-squares fitting of
	RAW ramps. We conclude that until and if the DCE0 SUR disparity
	can be calibrated, the first DCE taken by a command sequence
	for 24um should be discarded.
   Closure Plan: Test FSW in lab to see if the 1st DCE slope problem is
	a problem in the FSW. DK/TG (Ball).  Testing was done, and it
	appears this is a problem with the FSW algorithm. A fix needs
	to be implemented to FSW, probably post SV.

2. 24um POM contamination [ISA # 
   Status: Open
   Description: There are at least two dark spots that appear in 24um
	images taken in photometry mode.  The spots are ~3-4 pixels
	across, and ~20% dimmer than surrounding pixels. The move
	analogously to sources for CSMM moves, but do not move when
	the telescope nods, and so are attributed to debris on the
	pick-off mirror. Depending on the dither pattern used, these
	spots produce corresponding patterns of spots in mosaiced data
	(e.g. for small-field photometry they produce a trapezoid of
	dark spots in the lower-left corner). The contamination may
	also impact 160um images, as the same POM feeds that part of
	MIPS.
   Closure Plan: 
	See if a more elaborate flat-fielding approach corrects the 
	problem (DONE - Almudena showed that this works nicely at
	24um at least).
