Date: Wed, 9 Jun 2004 17:10:35 -0700 (PDT) From: John Zweizig To: Keith Riles Cc: kats@ligo.mit.edu Subject: Calibration time segments Hi Keith, Attached is the final list of missing calibration segment differences. I have listed the segments with missing calibration lines and indicated what change was made from v04 in terms of whether the segment need to be extended or if the previous segment was shortened. Sometimes adjacent segments are merged. When possible, I placed segment boundaries at minutes so that it won't affect the calibration calculation. The only exception is if the 1-2 seconds are missing. This should have a sufficiently small effect. I have noted these cases with "(ignore 1s missing)". Best regards, John ------------------------------------------------------------------------ Attached message: # This file started with a list of segments where the CDS second trends # indicated that there was no calibration line (H1:LSC-ETMX_EXC_DAQ< 1e-4). # I then removed all segments that: # a) have r/o errors in the Etmx_Exc channel # b) Have the minutes already covered in v04 # c) belong to segments tagged completely with "No_Calib" in v04. # d) correspond to missing or empty second trends. # 729880685 729881640 955 0 0 H1-044 merge H1-044ab 730231106 730237320 6214 0 0 H1-059 merge H1-059jk 730332638 730334640 2002 0 0 H1-061 extend H1-061a +60s 730425165 730425600 435 0 0 H1-069 extend H1-069a +60s 730691952 730692420 468 0 0 H1-087 extend H1-087a +76s 731626007 731626500 493 0 0 H1-109 extend H1-109c +60s 731806213 731806680 467 0 0 H1-117 extend H1-117a +24s 731878345 731878860 515 0 0 H1-120 extend H1-120a +60s 732294240 732294714 449 0 0 H1-140 shorten H1-140g -60s 734256946 734257440 494 0 0 H1-219 extend H1-219a +60s 734352709 734353142 433 0 0 H1-222 extend H1-222a +2s (ignore 2s missing) # # H2 # 729381000 729381110 110 0 0 H2-008 shorten H2-8a -60s 731052480 731052901 420 0 0 H2-165 shorten H2-165a -60s 731079120 731079694 574 0 0 H2-169 shorten H2-169a -60s 733085640 733086060 420 0 0 H2-311 shorten H2-311a -60s, extend H2-311b +60s 733116120 733116360 240 0 0 H2-313 shorten H2-313a -60s, extend H2-313b +60s # # L1 # 729331024 729332100 1076 0 0 L1-003 extend L1-3a +60s 729396789 729398280 1491 0 0 L1-015 extend L1-15a +60s 729536760 729537337 577 0 0 L1-038 merge L1-38bc 729587723 729588360 637 0 0 L1-055 merge L1-55ab, extend L1-55b +60 729704716 729705060 344 0 0 L1-072 extend L1-72a +60 731195735 731196000 265 0 0 L1-223 extend L1-223a +60 731340040 731340960 920 0 0 L1-254 extend L1-254a +60 731342760 731343047 287 0 0 L1-254 shorten L1-254b -60 731590315 731590380 65 0 0 L1-296 extend L1-296a +60 731651279 731651340 61 0 0 L1-303 extend L1-303a +60 731661656 731661720 64 0 0 L1-305 extend L1-305a +60 731738589 731738761 172 0 0 L1-315 extend L1-315a +1 (ignore 1s missing) 731766924 731767279 355 0 0 L1-324 extend L1-324a +19 731924866 731924940 74 0 0 L1-348 extend L1-348a +60s 731984816 731985360 544 0 0 L1-359 extend L1-359a +60 732023938 732024000 62 0 0 L1-367 extend L1-367a +60s 732206663 732206820 157 0 0 L1-394 extend L1-394a +60s 732339840 732339942 102 0 0 L1-405 merge L1-405bc 732513175 732513360 185 0 0 L1-433 extend L1-433a +60s 732556361 732558989 2628 0 0 L1-439 merge L1-439abc 732643897 732643980 83 0 0 L1-451 extend L1-451a +60s 733581939 733582020 81 0 0 L1-550 extend L1-550a +60s 733931740 733932780 1040 0 0 L1-577 extend L1-577a +60s
