This is currently just a holding area for Mike, until these are slotted correctly.

Integrate new table classes and measurement overhaul into pipe_tasks Feb 15 Feb 22 "Jim, Paul" 0% added 2/14; Winter2012d
Add persistence API support for tables and update ingest Feb 27 Feb 27 Serge 0% added 2/14; Winter2012d
update app code to use new config, butler, pipette (AP) Jan17 Feb2 Feb10 Feb17 Feb28 Mar2 Serge 75% split out on 2/21; moved to Winter2012d
Apps package reorganization Oct11 Oct31 Jim 25% Informal agreement by apps team on proposal, but implementation has been reschedule to be one of the last tasks in Winter2012 and proposal will be formalized then (implementation is expected to be very easy, but would disrupt other work)

Simon's notes on Stripe82:

Coadd delivery:
deliver camcol 3 (or all) for central 40 deg of stripe82 all bands to
NCSA with PSF information for matched models. -- Simon
dump data quality database. (Not neede anymore, since the MSSQL
Server will be queried directly ???)
tan-sip headers to NCSA. -- Simon
Deliver reference catalog of mean object positions and fluxes in all
bands. -- Becker
Make astrometry indexes from reference catalog. -- Simon

Test data:
iterate with Mario on the 10,000 chips for the monthly runs -- Simon

Coadd fix-up:
Interpolate nans (in cores of stars) -- Russell
Bilinear interpolation for mask planes -- Russell
Merge these changes with Hadoop coadd code -- ????

obs_sdss package:
 --camera geom for SDSS. -- Paul/Simon
 --mapper -- K-T
 --fpm to mask image -- Becker
 --psfField to LSST PSF -- ????
 --asTrans to TAN--SIP -- Rob G.

Operations on delivered stripe82 coadds:
Define quality metrics for coadds (for deep and template coadds) -- Zeljko
Run single frame measurement on fpCs with zeropointing and astrometry -- Becker
run detection on the stack -- Becker
 --make up a reasonable object schema
merge and generate objects from stacks -- Becker/Paul
forced photometry on object -- Paul
