Finding the position of MOSS relative to the dome

Alignment attempts

May 28, 2024

According to LOVE, the dome is at 284.57º. This seems about right by eye relative to the homing position, and they were running AuxTel last night.

Coarse aligning the telescope now.

Note: point_azel only works between plus and minus 270. 

By eye, with dome at 284.57 degrees, the correct telescope azimuth is ~-34 degrees. 

I am having trouble connecting to MOSS remotely (Royal TSX error is The connection's transport layer failed. (Error Code: FREERDP_ERROR_CONNECT_TRANSPORT_FAILED)). The Thorlabs light and computer power light are on, as is the ethernet cable light, but there was a power outage on the summit last night, so I am worried we have lost the IP address... Meghan also cannot connect. We'll get in touch with Hernan. Craig's best guess is that they moved all the AuxTel computers recently and that may have reset things.

Restarted the computer by pressing the power button on the side. It didn't help with the connection. But then Hernan suggested restarting the router, and that fixed the problem! Hopefully tomorrow I'll be able to do real alignment tests in the dome. If not, Friday should work.

Ran prepare for flats, so the dome is in position 2.57 degrees. So I think we want 2.6 + 39 = 41.6 in azimuth. Pointing to 26 in elevation, 41.6 in azimuth. - note - that's clearly not far enough. 

Landed on 45.6 after putting my hand in the beam path right above M3.

LATISS image 6 → 26 degrees elevation, 45.6 degrees azimuth

LATISS image 7 → 26 degrees elevation, 45.7 degrees azimuth

LATISS image 8 → 26 degrees elevation, 45.5 degrees azimuth

LATISS image 9→ 26.1 degrees elevation, 45.6 degrees azimuth

LATISS image 10 → 25.9 degrees elevation, 45.6 degrees azimuth

LATISS image 11 → 25.8 degrees elevation, 45.7 degrees azimuth - on the edge of it - have to switch to different mode

LATISS image 17 → 25.8 degrees elevation, 45.7 degrees azimuth - on the edge of it -2 s exposure w/ python pulses.py -n 6000 -d 0.005 -f 0.5

LATISS image 18 → 25.8 degrees elevation, 45.65 degrees azimuth - on the edge of it -2 s exposure - wrong way

LATISS image 19 → 25.8 degrees elevation, 45.75 degrees azimuth - on the edge of it -2 s exposure 

We have 3 of the 4:

Things have maybe shifted out of collimation

LATISS image 20 - az: 45.75 el: 25.78

Some weird reflection going on. Unfortunately, I don't have time to debug right now.
