    33=== GR  ===
    44
    5 June 29 with y band, followed by z band ~ 10 days of processing
     5June 29 - finished with g band in 14hr to 16 hr stripe. This data is believed to be compromised by the dark current model used for the older data.
     6
     7June 29 start GR of  14hr to 16 hr stripe  in y band, followed by z band ~ 10 days of processing.
    68
    79July 10 MD04 reprocessing
    810
    9 before July 15 MD10 reprocessing, and creation of template. Then incoming new MD10 data in OC142 will use this. MD 07, 08, 09 will continue with old pixel size and tessellation so as not to interrupt transient program.
     11before July 15 start MD10 reprocessing, and creation of template. Then the incoming new MD10 data in OC142 will use this template and will be done on the new tesselation.
     12The MD 07, 08, 09 will continue with old pixel size and tessellation so as not to interrupt transient program.
    1013
    1114on or before July 15 continue with GR with new dark model in i, r, and g.
    1215
    13 Schedule MD07 next as learn how long this takes. Then in parallel with GR, proceed with MD05 and 06. Try to ready to do MD 08 and 09 by the time they have finished for the year.
     16Schedule MD07 next as learn how long this 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.

    1518=== PSPS ingest ===
    1619
    17 start ingesting LAP dvo database now. When we have finished loading g and y band, approximately July 12, delete old data, and do the first merge/indexing. 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.
     20June 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.

    1922=== Caveats ===
    … …  
    2124People 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.
    2225
    23 The g, r, and i band data in this release will have higher noise than they should. It is believed this is a problem with the current dark current model being used for the old data we are re-processing.
    24 We will not save this pixel data, we will reproduce it with the correct dark model on the schedule above.
     26The 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.
    2527
    2628=== Towards Data Release 1.0 ===
    2729
    28 We will continue with GR as scheduled above, while working on the dark current model and outstanding photometry issues, including extended source photometry. (This does not include large galaxies, which are a special case for the next stage of development). When these are resolved (i.e "good enough") then the photometry analysis of the GR'd pixels will be redone. When this is complete we will do another deletion of what is in the PSPS and load the new results as Data Release 0.2. Maybe this becomes Data Release 1.0, we hope so, but it may turn out to take more than one release. These will be done in consultation with the Data Reduction and Verification Group, or DRAVG, with members at every institution.
     30We will continue with GR as scheduled above, while working on the dark current model and outstanding photometry issues, including extended source photometry.

When these are resolved (i.e "good enough") then the photometry analysis of the GR'd pixels will be redone. When this is complete we will do another deletion of what is in the PSPS and load the new results as Data Release 0.2.  Ideally we would be ready to do this by the time the first 2hr slice of 5 band data is re-processed. Maybe this becomes Data Release 1.0, we hope so, but it may turn out to take more than one release before we "freeze" the IPP code. These steps will be done in consultation with the Data Reduction and Verification Group, or DRAVG, with members at every institution.
