 Schedule MD07 next as we learn how long reprocessing an MD field takes. Then in parallel with 3pi GR, proceed with MD05 and 06. We would like to be ready to reprocess MD 08 and 09 by the time each has finished for the year.

 === PSPS ingest ===
 
-June 30 - we will start ingesting of all the currently completed GR (LAP) DVO database now. When we have finished loading g and y band, by approximately July 12, we will delete all the old data currently in the PSPS, and do the first merge/indexing of the completed GR data. Note the g,r,i,z,y initial LAP data will be there as well.  This will take about two days during which PSPS will be offline. Then PSPS will be online and available for consortium use on July 15.

+July 15 - PSPS will be online and available for consortium use on July 15. From then on until next stage in photometry discussed below, we will be in ~normal ingest rate as the GR proceeds so by the end of July there should be all five bands from the 14 to 16 hour RA slice. 
 
 === Caveats ===
 
-People should be aware that the ingested data has the same photometry issues as in the current processing. Thus it is not Data Release 1.0. It is data release 0.1. For details on the outstanding photometric issues see the PS1SC wiki DRAVG pages.

 The g, r, and i band data in this release will have higher noise than they should. (The only 5 band data will be the initial LAP release that overlaps some of Stripe 82). It is believed this is a problem with the current dark current model being used for the old data we are re-processing. We will not save this pixel data, we will reproduce it with the correct dark model on the above schedule.
