Checking to see if anyone had centered the optical levers in hopes to grab a spectra of the Commissioning Team's awesome new spectra, I found that - ETMY was still not centered, but with the corrected calibration - ITMY was centered, but had the old calibration (queue sad trombone). I've restored the ITMY calibration that I installed yesterday morning. I see that H2SUSITMY and H2SUSETMY were rebooted some time later in the day yesterday, according to the ops log, but I don't see any further details/aLOGs as to why... My guess is that safe.snap had not been updated since those calibrations were installed (though the right calibration stuck for ETMY...). I haven't gathered a new safe.snap myself, I'll will wait for local staff, as I'm not sure about the state of the cavity. But, when you do, remember there's a nifty script here: ${userapps}/release/cds/common/scripts/makeSafeBackup which can use to make a new safe.snap in the appropriate reboot location, and it also makes a copy in the appropriate userapps directory (with the model name appended), e.g. 0$ cd /opt/rtcds/userapps/release/cds/common/scripts/ 0$ ./makeSafeBackup sus h2susitmy 0$ which puts files in /opt/rtcds/lho/h2/target/h2susitmy/h2susitmyepics/burt/safe.snap and /opt/rtcds/userapps/release/sus/h2/burtfiles/h2susitmy_safe.snap
ha, that makes sense as the ETM oplev did give me any indicaiton I was yawing the test mass. In the early hour of the cavity locking I was trying to compensate for the pointing error casued by the heated ETM. Aiden mention that is was more in yaw (~25 urad), but the oplev wasn't able to show me my moves.
Now there are SUM indicators next to the QPD quadrant definitions, under the OPLEVINF button, in the lower left corner, on the SUS_CUST_L3_OPLEV.adl screens (which are linked off pf the QUAD OVERVIEW Screens). I attach screen shots of ETMY (Spot OFF the QPD) and ITMY (Spot ON the QPD). That bar is actually a live reading of the SUM channel, ${IFO}:SUS-${OPTIC}_L3_OPLEV_SUM_OUTMON, with limits from 0 to 10000 cts. (As shown, ITMY is aligned and has ~18k counts worth of light -- so a full green bar, and ETMY is not aligned, and has ~6 cts -- so no green bar). These is a good indication of whether you have light on the QPD or not.
