At 13:00 UTC this morning, H1 had relocked automatically all the way to NOMINAL_LOW_NOISE and the only thing preventing the observation intent bit to be set to OBSERVE was for the ADS to converge in order to switch over to the camera servos. Even though this is expected behavior, IFO_NOTIFY sent an alert to me as the operator because H1 had been in NLN for 3 minutes and the intent bit had not been flipped. After 13 minutes of waiting in NLN for the camera servos to turn on, the intent bit was set to OBSERVE automatically without any intervention.
Since we've seen ADS take up to 15 minutes to converge while in NLN before we can go to observing, I've increased IFO_NOTIFY's nln_not_obs timer from 3 minutes to 15 to avoid unnecessary notifications while ADS is converging as expected.
I've made this alert condition a bit smarter. IFO_NOTIFY will now wait for 20 minutes after reaching NOMINAL_LOW_NOISE for the camera servos to turn on before moving to 'ALERT_ACTIVE.' If ADS converges and the camera servos turn on before then (as we'd expect), the timer is stopped and a new 3 minute timer starts to indicate we've actually reached the point where nominally we would move to OBSERVE. If that timer expires, IFO_NOTIFY moves to 'ALERT_ACTIVE' to indicate something is preventing the move to OBSERVE.
