This is a policy announcement about how to handle GRB and SNEWS alarms in the control room. (GRB = gamma ray burst and SNEWS = SuperNova Early Warning System.)

In the event of a GRB/SNEWS alarm during ER7, a 1hour stand-down time (no hardware injections, no calibrations, transfer functions or elective interventions such as mini-commissioning studies or IFO tuning) is in effect.  The DMT-ANALYSIS_READY (and thus the intent bit) should remain high for this time on a best-effort basis.
