- Check Hanford IFO = True # Check for injections in the Hanford IFO frame files.
- Check Livingston IFO = True # Check for injections in the Livingston IFO frame files.
- IFO Coinc Time = 0.012 # Time window, in seconds, for coincidence between IFO injection events.
- Check ODC_HOFT = True # Check ODC-MASTER_CHANNEL_OUT_DQ channel in HOFT frames.
- Check ODC_RAW = True # Check ODC-MASTER_CHANNEL_OUT_DQ channel in RAW frames.
- Check ODC_RDS = True # Check ODC-MASTER_CHANNEL_OUT_DQ channel in RDS frames.
- Check GDS_HOFT = True # Check GDS-CALIB_STATE_VECTOR channel in HOFT frames.
- Check CAL_RAW = True # Check CAL-INJ_ODC_CHANNEL_OUT_DQ channel in RAW frames.
- Report Normal = True # Include normal (IFO-coincident (network injections only), consistent, scheduled, and of known type) injections in report
- Report Anomalous = True # Include anomalous (non-IFO-coincident (network injections only), inconsistent, unscheduled, or of unknown type) injections in report

Network and IFO Injections
Of the occurring scheduled injections, only two occurred as single-IFO injections:
- CBC 1134357333.938 (L1) (coherentbbh18_1128678894_)
- CBC 1134348934.048 (L1) (coherentbbh11_1128678894_)
All other scheduled injections occurred as H1-L1 coincident injections. The only UNSCHEDULED injections were 5 CALRESETs at L1 and 1 CALRESET at H1.
Discussion of Anomalies
The CALRESET injections have the same pattern of occurring with only certain paired combinations of the frame flags indicated by HWInjReport, as seen previously. However, all of the occurring scheduled injections have the anomaly of not occurring in the CAL-INJ channel and not having the TRANSIENT bit set to “off” to indicate the presence of a transient injection. They do occur, consistently, in the ODC-MASTER channel for HOFT, RAW, and RDS frames and the GDS-CALIB channel for HOFT frames.
Minor correction made to report. There were, in fact, 2 single-IFO injections that occurred, both in L1. I missed the second one due to an eyeball error.
As reported by Chris B. in https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=24282, the two single-IFO injections were the result of H1 losing lock.
The absence of occurrence of the injections in the CAL-INJ channel turns out to not be an anomaly but the result of a deliberate change to using the new CAL-PINJX_ODC_CHANNEL_OUT_DQ channel to record the information that was originally in CAL-INJ_ODC_CHANNEL_OUT_DQ. Currently, HWInjReport does not check the CAL-PINJX channel, however, it should not be difficult to add checking on this channel.
