  2. Data quality flags and detectors: web page
  3. Code review: At line 527 of xtimefrequencymap.


Attendance: Patrick, Gareth, Jolien, Xavi, Antony
  1. Ping on review summit.
  2. DQ flags - trying to settle on choices about whether to include a detector in an analyis.
    • Patrick's proposal: decide on network based on the amount of deadtime in cat2 and 3 vetoes -- if a few seconds, keep detector and suffer efficiency; if a few minutes, drop detector; only a couple of cases in between.
    • Previously: if a DQ flag is on during a GRB onsource interval, that detector isn't used for that GRB.
    • Jolien: doesn't like the implicit prior that GWB equally likely to be present during 180s window. DQ flag on at time of GWB is far more devistating than at beginning of window.
    • Suggestion: apply cat 1 and 2 flags, not 3 ("detection search" flags). Cat 3 are not really derived for GRB searches -- designed for ULs for all-time searches. Don't use them.
    • Different network for detection vs. upper limit. If cat 2 veto -- don't include detector in network for UL. Detection: do what is possible; report 50% efficiency as sensitivity; indicate what time was vetoed.
