PSNSC.wref.20170707 notes (draft)

best input stack limited to 40 inputs max --

• label PSNSC.wref.20170707, data_group PSNSC.wref.20170707h##, PSNSC.wref.20170707h##q2
• q2 (2nd level quality, poorer), may also be a q3 for lower quality
• data_group may also be LAP.PV3W or other included previously processed stacks

transition band -- DEC -25 to -35 -- processed last to generate stacks without a mix of ubercal and synthetic photometry calibration (when possible)

LAP.PV3W.20150312 -- will use by default for RA~8-16 -- will need to check/replace bad stacks and stacks with good_frac<0.9 (~15k)

cleanup of warps to proceed as regions complete to basically try to swap space for space so that stacks are distributed across data nodes (however most warps live on ipp100-104,118-122) -- therefore used ipp054-097 with space as direct targets rather than nightly processing

future stack updates/reprocessing -- as RA slice of 1-2hr sets, a improved stacks will be made -- criteria like good_frac<0.95, q2 check, Nin increase of some relative percent (TBD)

MOPS vs QUB WSdiff with w-band stacks -- moving versus stationary transients -- priority MOPS, QUB, other

• spatial coverage key for MOPS as most detections on sky pixels as long as diffs can be made well
• MOPS not limited by stack updates, QUB needs updates only during set season (avoid using inputs with events and changing mean levels)
