Here is the list of problems in SAS9 (unresolved SA8 problems appended to the end)

To be fixed for SA10

priority	problem	location	fixer	fixed?
	nigel found magnitude variation problems due to zeropoint offset	ipp	Bill	yes
	minor zeropoint issue	ipp / ubercal	Bill	yes
	stackdetections some have kronflux = 0 and some have kronflux = -999 why? all things with forced photometry have kronflux = 0 (other columns are set to 0 as well - basically kron* and moments* = 0) recommend they are set to null	cmf file	gene/bill
	ndetections != ng + nr + ni + nz + ny in many cases see SA9ndetections = we set ndetections = sum(nfilters)	dvo	heather/gene	yes
	stsci has object count integrity problems - investigate and compare to conrad s - factor 2 in det in obj_table see SAS9DataIntegrity - we think it is related to ipptopsps having filters that drop detections based on certain criteria	ipptopsps?	heather	yes
	xmeanpsfmag == xstackpsfmag discussions:right now, xmean is set to xstack when only stack detection. should be flag - see thread on this, we think it is ok	dvo	gene	yes
	apMag in StackDetectionFull needs exp time correction	ipptopsps	heather
	flxRn values in stackApFlux needs exp time correction	ipptopsps	heather
	check aperture values as per Roberto -we think this has been resolved		bill/gene	yes
	sdss - ps1 radial aperture magnitudes have offsets which change systematically with larger radius (via Roberto)	psphot	bill/gene	will not fix for this release
	position angle distribution for PSFs seems odd (via Nigel) --also present in LAP smf/cmf (needs to be fixed)		bill/gene	yes - in gene's branch needs to go in trunk
	conrad data integrity issues (the overlap object/stack/detections - see SAS9DataIntegrity -we understand them now		heather	yes
3	edge problem part 1: psps needs bigger ranges for SAS	psps	thomas
3	edge problem part 1: ipptopsps needs bigger ranges for SAS: recommend ra:[327:341] dec:[-7:7] to give a buffer	ipptopsps	heather	yes
3	edge problem part 2: integrity will always fail near edges heather thinks		ken	we decided we will accept that (3pi)
	-999s in ndetections : see SA9ndetections 12k from failed batch, 60k from ipptopsps not having enough ra/dec range, 2k need investigation,suspect from ipptopsps filters.		heather	yes
	ken's funny meanpsf vs kronpsf mag problem - flag issue, gene responded	ipptopsps	heather	yes
	remap of stack and p2 flags to infoFlags = (dbflags << 46 | flags2 << 32 | flags)	ipptopsps and wiki	heather	yes
	remove ipptopsps filters on detections etc and see if it improves integrity stuff- some important ones were kept (ie, delete null/zero objid and force un-queness on that)	ipptopsps	heather	yes

to be fixed

priority	problem	location	fixer	fixed?
1	need flag mask for stack only detections and forced photometry in stacks that are included by default		bill
	need flag masks for 'good' detections		bill?
3	need psvo-type flag mask generator for psps		bill/psps/roy?
	need descriptions of all flags	wiki	heather	yes PSPSFlags
	go over HeathersPSPSVerificationPage and determine the columns that need to be dropped or filled		heather/gene/ken
	stsci likely has other issues that need to be added to this wiki		heather
	need description of xflags (object table)	wiki	heather	yes PSPSFlags
	Object has unfilled columns: projectionCellId, stackVer, consistency, updated, varFlag		ken/gene
	DetectionFull has unused columns: activeFlag, historymodnum		ken/gene
	StackDetectionFull has unused columns: primaryF, apmagerr, kronraderr, activeflag, historymodnum		ken/gene
	stackDetectionFull = skycell column not set properly		heather/conrad
	Object has unused w band nw, wMean,wMeanPSFMag, etc		gene/heather
3	John Lacy extended model radii problem - see DRAVG pages	ipp	gene
