We were open for ~2.5 hours doing various binocular tests. Eventually the clouds and wind forced us to close.
Clear sky in afternoon, but clouds and wind are increasing by sunset.
02:05 Clouds are thinning a bit, and winds are still slightly below 20 m/s, so we are opening
Authorize LUCI @ LFBG monocular
02:15 ACQUIRE Preset IE=-36 CA=-9
02:18 ACTIVE Preset BS9188 - seeing is 1.5 - 2 arcsec.
Authorize IRTC @ RFBG along with LUCI @ LFBG
Apply the RZ +5.12 deg global offset to DX M3
02:29 Left Async ACTIVE preset
02:31 Right ACQUIRE, then Left ACQUIRE
02:38 spiral both sides to move mount
then paddle to center each side. SX IE=-37.8 CA=-8.4 DX IE=47.46 CA=-66.76
Offset 0 -30 on left - this makes copointing warnings from both sides (one warning would be sufficient).
Issue: DX side is having problems with collimation. It looks like M2 is not putting any astigmatism LUT, and the DX primary has saturated at -20000 Z6
and is also applying -17000 Z5.
We called Julian to see if he can turn on the LUT. DX shell RIPs.
SX complaining about guide star not stable after 2 iterations. See Issue 4434.
02:47 Async ACTIVE presets each side
03:09 offset 0 0
03:10 Right shell RIPs
Julian restarts the arbitrator and everything.
03:45 Corrected the guide correction factor and guidecam_clipping and guideWindowSize in LUCI_IRTC_R.cfg
03:55 Resend right side preset after restarting GCSR. Right guide box parameters are now correct, but guide box as drawn on the acq image is still different (it took another preset to be redrawn?).
04:xx DX M2 hits +RY limit. Adjust Xglobal offset to be more negative. Xglobal=-1.5 but that is still not enough.
04:15 Xglobal to -1.75
04:20 SYNC ACTIVE presets to BS9107 - but no star? Geno's getting good practice with binocular spiralling and acquisition.
LUCI_L.cfg: guidecam_ROI "16 40 536 508"
LUCI_IRTC_R.cfg: guidecam_ROI "18 16 526 510"
LUCI_IRTC_L.cfg: guidecam_ROI "16 40 536 508"
04:47 Closing as the clouds are getting seriously thick.
Closed Dome Binocular Testing
05:34 SYNC ACTIVE presets
05:38 Turn on fake guide stars in gcs.conf. Restart GCSs. Working on Issue 4431.
05:40 SYNC ACTIVE presets
05:48 Took out the guidecam_ROI parameters to see if they were blocking the drifting hotspot. Restart GCSs.
Aha! Not guidecam_ROI, but guidecam_clipping is the problem.
05:56 Took out guidecam_clipping. Restart GCSs.
05:58 SYNC GUIDE presets
Yes, the drifting hotspot blockage is caused by the guidecam_clipping parameter. Added note to Issue 4431.
