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 [[wiki: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 [[wiki: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 [[wiki: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 [[wiki: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''' ||
