Science Verification

Science Verification provides an end-to-end test of all the systems needed to actually conduct the survey, both on the mountain and elsewhere. Successfully passing the formal acceptance requirements is a necessary condition for DES to begin (along with corresponding acceptance tests of DES DM and the Community Pipeline).

SV Requirements and Goals

Resources needed for Req/goals. Make a new page for each Req/goal and link it here. (OK to combine similar req/goals onto one resource page).

SV Software

SV will use a stand-alone version of the DES DM software stack. Work is going on at Fermilab to package the software for easy distribution for use not only at CTIO but also machines at the home institutions of SV Squad members.
Robert and his team at NCSA are currently working on version 7.0 of the stack which we plan to use for both DC7 and science verification. Brian and his team at Fermilab have successfully compiled version 6.3.2 under RHEL/SL 6 and 64 bits. An intermediate version - the postgres branch of the svn repository - has been compiled at OSU.

A manifest of codes (beyond the DM pipeline) needed to execute SV - plus the ones we will provide for Commissioning - is now posted as docdb-6629. Please help complete this spreadsheet with codes you have written or will need to write.

Observations: Locations of 1st year fields

West SPT Deep field: 
     −17 ≤ra≤ 2 −58 ≤dec≤ −49        10 tilings, skip if SV stars after Nov 7
Spectroscopic Training field: 
    14 ≤ra≤ 40 −7 ≤dec≤ 3                10 tilings, skip if SV stars after Dec 7
Maximum Visibility field: 
    65 ≤ra≤ 90 −58 ≤dec≤ −48          10 tilings, skip if SV stars after Dec 14, or Dec 21, or... then go to Cosmos/Mini Survey
SPT Main Survey area:
     20 ≤ra≤ 105 −65 ≤dec≤ −40        2 tilings, use extra time to get, so area observed drops as SV starts later

    We are fine-tuned this page during year zero. Soon there will be a DES specific page so that DECam User's don't get caught up in DES-only procedures.
