# This file contains a list of "bad-flags", with the numerical value in the # data quality bitmask. The numerical value is expressed as a power of 2. # The flags are used in the segment log files. For example: # To mark all of a segment as bad: # *BAD(MICH_FILT) # To mark the first part of a segment as bad: # *BAD(OUTSIDE_S2) -729273613 # To mark the last part of a segment as bad: # *BAD(OUTSIDE_S2) 734367613- # To mark an interval within a segment as bad: # *BAD(MISSING_RAW) 733121837-733121862 # # bad-flag bitval description OUTSIDE_S2 2^0 Data is outside of official S2 time interval MISSING_RAW 2^1 Raw data is missing MICH_FILT 2^2 One or more MICH filters was not in its nominal state # # Flags added for version 2 segments # AS_PD_SATURATION 2^3 Antisymmetric port photodiode saturated ASQ_LARGEP2P 2^4 Large peak-to-peak range seen in AS_Q at end of lock DAQ_DROPOUT 2^5 Dropout (or apparent dropout) in data acquisition system NONSTAND_CTRLS 2^6 Non-standard controls affecting calibration / couplings # # Flags added for version 3 segments # MISSING_RDS 2^7 RDS is missing (unrecoverable because of technical problem) INVALID_TIMING 2^8 Timing believed to be unreliable NO_CALIB_LINE 2^9 Calibration line turned off (superseded by NO_CALIB in version 4) INVALID_CALIB_LINE 2^10 Problem with calibration line strength CALIB_LINE_NO_RDS_V03 2^11 Problem with accessing RDS for calib info (version 3, may be superseded later) ASQ_OUTLIER_CLUSTER 2^12 Cluster of large AS_Q outliers in short time interval ASQ_OUTLIER_CORRELATED 2^13 Large ASQ outlier correlated with outlier in auxiliary IFO channel (use with care) ASQ_LOWBAND_OUTLIER 2^14 High noise below 100 Hz in AS_Q ASQ_UPPERBAND_OUTLIER 2^15 High noise in 100-7000 Hz in AS_Q DAQ_REBOOT 2^16 One or more DAQ crates rebooted # # Flags added for version 4 segments # NO_CALIB 2^17 Calibration line turned off LOW_CALIB 2^18 Calibration line strength too low GROWLY 2^19 "Growly" noise in interferometer (200-400 Hz RMS too high for at least 5 minutes) # # Flags added for version 6 segments # ACOUSTIC_ELEVATED 2^20 Elevated acoustic noise in the 62-100 Hz band AIRPLANE 2^21 Acoustic noise in the 62-100 Hz band likely due to a nearby airplane BEFORE_REINJECTION 2^22 Period before reinjection of current into Allegro transducer AFTER_REINJECTION 2^23 Period after reinjection of current into Allegro transducer AZIMUTH_252_XARM 2^24 Allegro bar aligned with LLO X arm AZIMUTH_297_NULL 2^25 Allegro bar aligned with LLO arm bisector AZIMUTH_342_YARM 2^26 Allegro bar aligned with LLO Y arm REF_OSCILLATOR_RESET 2^27 Allegro reference oscillator phase under adjustment NO_CALIB_DATA 2^28 Allegro calibration data not available or calibration unreliable
