I. Working Source Databases (review from June 2000 ERB)

• Contents of the Working Source Databases (Skrutskie)



• Release Options and Resources (Cutri)



• WSDBs can be made available to astronomical community via via IRSA interface, Caveat Emptor, with existing resources.
  
  
  • Contents of WSDB's "beyond Catalogs" characterized in appendices of 2MASS Explanatory Supplement
  • ``User-friendly" flags (as in Catalogs) being added to WSDBs during final processing
  • Long-term curation costs to IRSA
• 
  
  
• Any additional processing or filtering of WSDBs, or release in forms other than IRSA on-line tools will require additional resources
  
  
  • Amount will depend on scope of additional processing or release media
  • e.g.Duplicate source identification, off-scan artifact flagging, source combination, DVD or tape distribution...
  • Conservative estimate of maximum effort is 6 full-time staff for 8 months, and up to $50k for distribution costs.

II. Calibration Data

• Forty 1^o x 8.5' Calibration Fields observed 800-3000 times during survey. Processed with same pipeline as Survey data, but less scrutinized for overall quality



• Calibration Source Working Database contains 1.9e8 point and 8e5 extended sources



• Highly redundant detections useful for variability studies, proper motion measurements, etc



• Release options the same as for Survey Working Source Databases. Additional costs ~1/6 of WSDB

III. "Deep" Survey Data

• Special observations of Lockman hole, Chandra south, Abell clusters, star forming regions, 166 deg² covering SMC and 489 deg² covering LMC made using 6x normal survey exposure time (~1 mag deeper)



• Preliminary processing of data made with pipeline (adjusted only for exposure time difference) validated performance



• Pipeline "tuning" for deep survey data required for optimal processing would require 3 months effort by 5 engineers
  
  
  • Artifact identification
  • Increased backgrounds
  • Test and Validation


• Processing time ~2 months, with 5 person OPS and QA staff



• FPG - Can range from "release Working DB" to "full Catalog generation". Resource requirements will vary accordingly, but max effort would require 5-6 full-time staff for up to 3 months.

IV. Plan

• Per the Board's recommendation, the Project desires to release all of the ancillary data products in forms most useful to the community, as schedule and resources permit



• Preparation and release of the final survey deliverables has top priority



• WSDB access can be enabled through IRSA with current resources



• We will prepare a proposal for additional funds to enable some processing of WSDBs before release, and processing and release of Deep survey data
