SV Charge

The DES Project Director has presented the SV Squad with the following charge:

  1. developing a written SV plan (building on the efforts already underway by the WGs for Data Challenge/Acceptance Testing) that specifies the Science Requirements-derived critical tests to be performed during SV, the criteria for success, who will be responsible for carrying out each test, and the data sets, analysis tools and DESDM outputs needed to perform the tests. In putting together the plan, they will concentrate on tests that can be performed with the limited data to be obtained during SV. They will also look afresh at the DES Science Requirements to assess them for testability. To the extent practical, SV analysis tools should be checked into a code repository so results can be independently verified.
  2. working with the DESDM project management and DES Project Scientist to review and finalize the required DESDM capabiliites for commissioning, SV, and early operations, including DESDM outputs, required processing timescales, and data accessability
  3. reviewing the SV Observing Plan (Doc Db 6255) and recommending changes as necessary to carry out the SV plan
  4. writing an SV report to be delivered to the DES Director prior to the end of the 20-night SV period that assesses the DECam/telescope performance on these tests and makes a determination whether the system is delivering survey-quality data. Where data quality is found deficient, the report will attempt to diagnose cause(s) and make a recommendation as to whether the start of survey operations should be delayed in order to ameliorate the problem. Interim results should be posted on the SV redmine wiki for access by collaboration scientists.
  5. SV squad members will draw on efforts of SWG members who are not part of the core SV team as needed.
  6. SV squad leaders to maintain communication with and report regularly to the Science Committee, DES Project Office, and CTIO Instrument Scientist. One communication mechanism will be a reconstituted DES Executive Committee, of which they will form a part.
  7. SV squad leaders to work with DES Operations Manager and DES Deputy Director to develop a plan for on- and off-mountain personnel during SV operations, including any necessary training of observers and coordination of Run Managers during SV. This will include specification of any additional resources needed by the SV team to complete its tasks.
  8. SV squad leaders will work in close coordination/communication with NOAO SV Lead Dara Norman
  9. This initial SV phase will be completed once DES survey operations start. Thereafter, SV will focus increasingly and over a longer timescale on testing DESDM. The make-up of a group to carry out these longer timescale tasks TBD.

Note that the tests to be performed during SV will focus primarily on data quality and operational efficiency (e.g., data quality vs slew/settle times) as opposed to DESDM requirements, though the report should comment on DESDM operational readiness as well.
