As per LIGO-M1500250, H1 has now been put into "OBSERVATION MODE". This means:
The ODC-OPERATOR_OBSERVATION_READY bit, which is set to "Undisturbed" by the operator on the GUARD_OVERVIEW screen, will now be automatically unset by the Guardian IFO top node if any of the monitored guardian nodes drop from OK==True.
The most likely ways that this can happen are:
Operators must be aware that the INTENT bit must be manually reset after any of these changes.
The list of Guardian nodes being monitored is stored in:
USERAPPS/sys/h1/guardian/IFO_NODE_LIST.py
The current monitored node list is:
ALIGN_IFO ALS_COMM ALS_DIFF ALS_XARM ALS_YARM HPI_BS HPI_ETMX HPI_ETMY HPI_HAM1 HPI_HAM2 HPI_HAM3 HPI_HAM4 HPI_HAM5 HPI_HAM6 HPI_ITMX HPI_ITMY IMC_LOCK ISC_DRMI ISC_LOCK ISI_BS_ST1 ISI_BS_ST2 ISI_ETMX_ST1 ISI_ETMX_ST2 ISI_ETMY_ST1 ISI_ETMY_ST2 ISI_HAM2 ISI_HAM3 ISI_HAM4 ISI_HAM5 ISI_HAM6 ISI_ITMX_ST1 ISI_ITMX_ST2 ISI_ITMY_ST1 ISI_ITMY_ST2 OMC_LOCK SEI_BS SEI_ETMX SEI_ETMY SEI_HAM2 SEI_HAM3 SEI_HAM4 SEI_HAM5 SEI_HAM6 SEI_ITMX SEI_ITMY SR3_CAGE_SERVO SUS_BS SUS_ETMX SUS_ETMY SUS_IM1 SUS_IM2 SUS_IM3 SUS_IM4 SUS_ITMX SUS_ITMY SUS_MC1 SUS_MC2 SUS_MC3 SUS_OM1 SUS_OM2 SUS_OM3 SUS_OMC SUS_PR2 SUS_PR3 SUS_PRM SUS_RM1 SUS_RM2 SUS_SR2 SUS_SR3 SUS_SRM SUS_TMSX SUS_TMSY TCS_ITMX
Note to Operators: ODC-OPERATOR_OBSERVATION_READY bit, which is controlled by the button labeled "undisturbed" on the GUARD_OVERVIEW.adl screen, is distinct and different from the H1:ODC-OBSERVATORY_MODE channel, which is set from the OPS_OBSERVATORY_MODE.adl screen. The ODC-OBSERVATORY_MODE describes the activity (wind, preventative maintenance, commissioning, etc.) and is used to generate our time spent pies. These are summarized in the DetChar summary pages at:
https://ldas-jobs.ligo-wa.caltech.edu/~detchar/summary/day/20150817/lock/operating_mode/
The Operators' priority is to the GUARD_OVERVIEW undisturbed button, which signals the readiness for scientifically valid observing. The selection of the LHO operating mode to "OBSERVING" (in the OPS-OBSERVATORY_MODE.adl screen) can be done after the pressing of the "undisturbed" button. After a lock loss, the operator should select the appropriate LHO operating mode activity.
