Summary

Doug and John have completed the AGW2 alignment this evening in decent seeing. Guider hotspot, pupil hotspot, probe at rotator center have been updated. Binodal aberration has been verified to be small relative to the noise. In PSF, primary astigmatism LUT has been turned off, and focus global offset set to -3.5 mm.

We've handed back to DaveT and Barry at 06:15 UT to take a set of LUCI2 transformation data.

Details

03:30 Doug and John start working really remotely from the main lodge at Lake Arrowhead (Bruin Woods). It is the first time I have ever observed from a room with a fireplace.

AGW2 Guide Hotspot Alignment

DX Guide Hotspot starts at 278,235 pixels.

03:45 280,235
03:49 275,235
03:52 275,233
03:54 275,237

The adopted guide hotspot of 275,237 was installed in LUCI_R.cfg guidecam_hotspot_x,y. The adopted wfs "hotspot" of 276,263 was installed in LUCI_R.cfg WFScam_hotspot_x,y.

AGW2 Probe Alignment to Rotator Center

04:xx ACTIVE preset on-axis to BS9188 at EL=81

04:10 remove M1 astigmatism LUT since there is no AdSec, and restart PSF. This was done for both LUCI2 and MODS2. Old coefficients were -1.7e4 and 2.0e2.

JMH also fixed the collimation model to include the Zglobal=-3.5 mm needed for the rigid secondary.

04:xx guider image 0001 x,y=105,122
double for binning to 210,244
add detsec offsets to 227,259
need +48,-22 pixels
need +2.4,-1.1 arcsec
adjust -98 counts, +660 microns
ROT -33701 ---> -33799, RAD 417722 ---> 418322

04:51 rdwrconfig -u 2

04:xx guider image 0002 x,y=125,112
double for binning to 250,224
add detsec offsets to 267,239
The above values were adopted in oacontrol.conf
