PSST QUB requirements and notes (draft) --


Processing products --
 * WS diffim catalogs on datastore
 * PSS and rapid updates for historical stamps (warp+stack+diff)

Processing timescale -- ideal and last cutoff times for diffim catalogs to be available
 * 


Tasks to do -- in order of possible accomplishment
 * switch to PV3 stacks for grizy -- requires new ops tag, still some bugs in it
 * gpc2 import of PV3 stack products -- requires new ops tag and then export/import of gpc1 stack rows to gpc2

 * WSdiff daily test set -- 

 * PV3 w-band stacks -- 

 * gri synthetic w-band stacks for all sky --
