X-Pipeline Review Meeting Monday 23 March 2009 09:00 Pacific / 12:00 Eastern

Agenda: Monday 23 March 2009 09:00 Pacific / 12:00 Eastern

  1. At the LVC meeting Jolien and Gareth completed review of xmakegrbwebpage.m and xtunegrbwebpage.m - no bugs found.
  2. Link to projects/xpipeline/s5/grb/segments dir of lscdocs.
  3. Brief discussion of changes to paper.

Attendance: Patrick, Gareth, Jolien, Xavier
  1. At the LVC meeting Jolien and Gareth completed review of xmakegrbwebpage.m and xtunegrbwebpage.m - no bugs found.
    • True.
  2. Link to projects/xpipeline/s5/grb/segments dir of lscdocs.
    • Cat 1 DQ: don't analyze data; Cat 2 DQ: discard triggers in post-processing. DQ and Vetos treated identically.
    • Choosing IFO networks [ HTML ]...
      	i. No deadtime incurred by category 1 flags in an interval [-128,+128]s about the GRB trigger time. X-pipeline requires 256s in order to estimate the PSD, category 1 flags raised within these 256s will lead to inaccurate/incorrect PSD estimation.
      	ii. Less than 9s (5%) deadtime incurred by category 2 flags in the onsource, i.e., an interval [-120,+60]s about the GRB trigger time. We tune our glitch rejection cuts using calculation of the 90% UL on hrss amplitude. If we lose much more than 5% deadtime in our (dummy) onsource we may not be able to accurately estimate the hrss amplitude leading to 90% detection efficiency.
      	iii. No deadtime incurred by category 2 flags in an interval [-5,+1]s about the GRB trigger time. Many GRB models predict similar arrival times of EM and GW emission from a GRB. We therefore require that inclusion of an ifo does not kill times close to the GRB trigger time.
      	
      NOTE: use both "veto" and not veto files from Laura's page; also use (real) veto files from Lindy's.
    • cat2vetosegments collects all the "veto" files (those that list deadtimes).
    • Lindy's files overlap between y1 and y2, but he specifies a break-point. tStartYr2Tuning = 847555200; %-- (Nov 14 2006 15:59:46 UTC)
  3. Brief discussion of changes to paper.
