PSNSC_NCU requirements and notes (draft) --

NCU observations -- processing needs to be finished by early morning for MOPS to use for NEO

• obs_mode NCU -- new, possibly start Oct. 24 2016 HST (not start after 11/1 HST?)
  • 4 chunks (returns) -- NCU1B...NCU4B; NCU1A...NCU4A -- see night sequence below
    • B=color set, sequence wgwrwiwz per chunk (8 targets each)
    • A=w-band only, wwwwwwww (8 targets each)
  • 8 targets (fields) -- NCU1.1...NCU1.8; NCU2.1...NCU2.8; NCU3.1...NCU3.8 ; NCU4.1...NCU4.8 (chunk#.target#)
    • 4 above, 4 below ecliptic centered around opposition
  • no dither in a night (no rotation like MD/QUB/FSS) -- offset done each night mean motion retrograde (W along ecliptic, ~0.3 degrees?)
  • exposures per field --
    • griz --
      • A: 1/chunk * 4 chunks = 4
    • w --
      • B: 4/chunk * 4 chunks = 16
      • A: 8/chunk * 4 chunk = 32
  • 4 sequential nights, ~6 hr/night
  • exptimes wgriz: 60,120,120,120,180s
  • run queue sequence then
    • night 1: NCU1B, NCU2B, NCU3B, NCU4B -- only color queue -- return to exact position (no dither)
    • night 2: NCU1A, NCU2A, NCU3A, NCU4A -- only w queue -- return each time to position (no dither), but has target/field center motion shift from previous night
    • night 3: NCU1A, NCU2A, NCU3A, NCU4A -- only w queue -- return each time to position (no dither), but has target/field center motion shift from previous night
    • night 4: NCU1A, NCU2A, NCU3A, NCU4A -- only w queue -- return each time to position (no dither), but has target/field center motion shift from previous night
  • chunk name (QUEUEID keyword in headers) -- may want to add filter here like in comment string below
  • target name (OBJECT keyword in headers) -- NCU(chunk#.target#) -- may be enough to trigger for WW per chunk (8 visits) rather than all night (32 visits), may also trigger .multi case too over the multiple nights...
  • comment string -- needs to be descriptive and easily parsed, need to check with MOPS for WS grouping/parsing issues (spaces) --
    • B: old format: NCU1B w4 NCU1.1 -- (chunk) (filter)(visit# for w only) NCU(chunk#.target#) -- want to add "visit #" at end of comment (1-4), move filter to chunk name
    • B: new format: (chunk).(filter) NCU(chunk#.target#) visit (visit # in chunk)

    • A: old format: NCU1A NCU1.1 -- (chunk) NCU(chunk#.target#) -- add "w" so similar format for B and "visit #" at end of comment (1-8), move filter to chunk name
    • A: new format make similar: (chunk).(filter) NCU(chunk#.target#) visit (visit # in chunk)

• chip->warp normal stdscience pantasks as with xSS products (ipp-20141024 tag)
• WSdiff runs in ~ippmops/stdscience_ws with modified ipp-20141024 ops tag to make uncompressed WSdiffs (like FSS)
  • larger volume, may need more nodes -- must be uncompressed for MOPS stamps since large data volume
  • default detection @5-sigma while WWdiff is <5-sigma and may need to be adjusted --
• WSdiff published to normal MOPS datastore location?

Processing products -- czar needs to make sure all faults and issues are cleared daily (early morning) for NCU.* products

• chip-cam-warp -- NCU.nightlyscience -- nightly
• warp-stack diffims -- NCU.WS.nightlyscience -- nightly
• publishing of WSdiffs -- (need datastore location to use from MOPS) -- nightly
• manually done -- not czar responsibility
  • nightly stack -- NCU.nightlyscience -- nightly, manually done to avoid any poor images
  • stack-stack diffims -- NCU.SS.nightlyscience -- nightly, likely automatic possible once manual stacks made
• stamps -- TBD

Cleanup --

• chip -- 1 day?
• warp -- 2 days (no specific requirement?)
• WSdiff -- 1 day? uncompressed so likely will need to limit and just do updates for stamps
• publishing WSdiff catalog bundles --
• pstamp -- manual cleanup like other ps_ud_%

Tasks to do --

• verify w-band stacks okay along ecliptic for opposition end October
• check processing rate/nodes for WSdiffs
• MOPS interested in SSdiff?
• publishing location for WSdiff by MOPS preference -- IPP-MOPS-TEST or IPP-MOPS-WS -- unique set so likely normal location
• detection threshold -- 5-sigma default but may need to lower?
