The re-calibrated C01 hoft data generated by DCS is ready for use. It is available via NDS2 and will be published into LDR soon. The calibration factors were not applied when generating this version of hoft. The calibration group will comment separately on the uncertainties in the C01 calibration. (The calibration group is working on applying the calibration factors which will result in another version of hoft.) 1. The times the re-calibrated C01 hoft cover are: H1: 1125969920 == Sep 11 2015 01:25:03 UTC to 1128398848 == Oct 09 2015 04:07:11 UTC L1: 1126031360 == Sep 11 2015 18:29:03 UTC to 1128398848 == Oct 09 2015 04:07:11 UTC as per these alogs, https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=22392 https://alog.ligo-la.caltech.edu/aLOG/index.php?callRep=21464 and as documented here: https://wiki.ligo.org/Calibration/GDSCalibrationConfigurations https://wiki.ligo.org/LSC/JRPComm/ObsRun1#Calibrated_Data_Generation_Plans_and_Status https://dcc.ligo.org/LIGO-T1500502 2. Users should use C00 hoft and DQ flags before/after the above times. This means the O1 analysis chunk including Oct 09 2015 04:07:11 UTC might need parts a and b, using C01 and C00 data respectively. 3. These C01 specific DQ flags exist: H1:DCS-MISSING_H1_HOFT_C01:1 H1:DCS-SCIENCE_C01:1 H1:DCS-UP_C01:1 H1:DCS-CALIBRATED_C01:1 H1:DCS-ANALYSIS_READY_C01:1 H1:DCS-INVALID_CALIBRATED_DATA_TST_C01:1 H1:DCS-INVALID_CALIBRATED_DATA_THREE_C01:1 H1:DCS-CALIB_FILTER_NOT_OK_C01:1 L1:DCS-MISSING_L1_HOFT_C01:1 L1:DCS-SCIENCE_C01:1 L1:DCS-UP_C01:1 L1:DCS-CALIBRATED_C01:1 L1:DCS-ANALYSIS_READY_C01:1 L1:DCS-INVALID_CALIBRATED_DATA_TST_C01:1 L1:DCS-INVALID_CALIBRATED_DATA_THREE_C01:1 L1:DCS-CALIB_FILTER_NOT_OK_C01:1 Summaries of the % "live" time are here: https://ldas-jobs.ligo.caltech.edu/~gmendell/DCS_SegGen_Runs/H1_C01/html_out/Segment_List.html https://ldas-jobs.ligo.caltech.edu/~gmendell/DCS_SegGen_Runs/L1_C01/html_out/Segment_List.html And due to non-zero dataValid flags, L1:DCS-ANALYSIS_READY_C01:1 will not include these segments, 1127128496 1127128592 96 1127353008 1127353104 96 1127387760 1127387856 96 1127435760 1127435856 96 1127687856 1127687952 96 1128122032 1128122075 43 1128122086 1128122128 42 1128320816 1128320912 96 Total duration = 661 seconds. but will gain these, due to gaps that have been filled in: 1126981012 1126981079 67 1126981095 1126981474 379 1126981888 1126983568 1680 1126989208 1126989232 24 Total duration = 2150 seconds.

For analysis ini files, i. The frame-types are H1_HOFT_C01 and L1_HOFT_C01 ii. The STRAIN channels are: H1:DCS-CALIB_STRAIN_C01 16384 L1:DCS-CALIB_STRAIN_C01 16384 iii. State and DQ information is also in these channels: H1:DCS-CALIB_STATE_VECTOR_C01 16 H1:ODC-MASTER_CHANNEL_OUT_DQ 16384 L1:DCS-CALIB_STATE_VECTOR_C01 16 L1:DCS-CALIB_STRAIN_C01 16384 The bits in the STATE VECTOR are documented here: https://wiki.ligo.org/LSC/JRPComm/ObsRun1#Calibrated_Data_Generation_Plans_and_Status
