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 end Oct 2016 
  * 4 chunks (visits/returns? dither?) -- NCU1B...NCU4B; NCU1A...NCU4A 
     * 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?
  * offset only dither (no rotation like MD/QUB/FSS) -- is the offset in the queue files yet? is the dither added to each visit?
  * 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 sequence then? or is color done each night? where is the dither offset added, for each chunk?
   * night 1: NCU1B, NCU2B, NCU3B, NCU4B
   * night 2: NCU1A, NCU2A, NCU3A, NCU4A
   * night 3: NCU1A, NCU2A, NCU3A, NCU4A
   * night 4: NCU1A, NCU2A, NCU3A, NCU4A 
  * comment string -- needs to be descriptive and easily parsed
   * B: NCU1B w4 NCU1.1 -- (chunk) (filter)(set number for w) (chunk#.target#) -- 
    * need to replace set number with (visit number) at end of all comments? is this tricky for generating/running queue? --
   * A: NCU1A NCU1.1 -- (chunk) (chunk#.target#)
    * add w for filter even though default? --
    * add (visit number) at end of all? is this tricky for generating/running queue? --
 * 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
 * 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
