Subject: 2.5m obslog 20211016 (SJD 59504) From: dgatlin@apo.nmsu.edu Date: Sun, 17 Oct 2021 10:32:25 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday October 16, 2021 (SJD 59504) ---- Observing Team ---- Dylan Gatlin Audrey Oravetz (R) Jose Sanchez-Gallego ---- Observing Plan ---- Alt fiducial data and boss testing ---- Observing Summary ---- With Jose's help, we worked on some issues with the bossICC. The final version Jose made before he logged off has yet to produce an error. We also took an altitude fiducial dataset. Below is the important info for the fiducial set: at start: temp: 8.94 time: 1634451187 at end: temp: 8.00 time: 1634452005 Notes: - I had an issue opening the cabinet with the fan switch on the left side as soon as you enter the lower enclosure. The lock mechanism loosened itself, which caused the whole mechanism to flip upside down, and couldn't be turned. After fighting it a bit, I was able to open it up and tighten the mechanism properly. You just need to hold the key in the right orientation and use a phillips screwdriver on the other end. I think it now rotates the opposite direction of how it used to. - We have a new version of the bossICC trying to fix the sp1mech issues. There was an issue where the sp1mech would send a byte string of two integers encoded as hexadecimal numbers. For some (but not all) possible values, they couldn't be safely decoded to utf-8. Once we identified the issue, we found it in a variety of other places throughout the actor that needed to be fixed. ---- Observing Log ---- APOGEE cals started Mirror numbers in spec BOSS test bias and 20s dark okay Jose logged on to help us diagnose the BOSS issues we've been having. He loaded the Python 2 version of the bossICC and we took some exposures using that to see if the issue was from the Python 3 upgrade. We took sets of 60 biases. The sp1daq failed once, giving us a netburner issue. 02:24Z began ventilation for a set of altitude fiducial data. We have been running a variety of looped commands to test the Python 2 version of the bossICC. We had done `boss exposure bias` for 60 loops twice, and various iterations of boss moveColl spec=sp1 a=200 b=200 c=200 boss moveColl spec=sp1 a=-200 b=-200 c=-200 After trying a combination of the two with a boss bias and then two collimator moves, we had not seen any dropouts, other than the one netburner issue with sp1daq. We expected far more dropouts than we got, so we decided to switch to the bossICC in Python 3 and rerun boss exposure bias boss moveColl spec=sp1 a=200 b=200 c=200 boss moveColl spec=sp1 a=-200 b=-200 c=-200 for 60 loops. We saw an sp1mech dropout in our second loop. We were able to get sp1mech to drop out quite regularly and quickly. Jose noticed some alerts he didn't see before, and started working on a new boss version. The errors had to do with Python 3's utf-8 strings v byte strings. When Jose was working on the bossICC, I went outside to take an altitude fiducial data set. at start: temp: 8.94 time: 1634451187 at end: temp: 8.00 time: 1634452005 06:39Z Turned off ventilation Jose created a new version of the bossICC called 6.0.1-alpha.0 and boss.specMec 3.0.4. It took a bit working through various errors in the new changes. Once those issues were sorted out, we ran the same looped command 70 times without errors. ---- Mirror Numbers ---- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A: 0.0110 0.0080 Axial B: 0.0380 0.0330 Axial C: -0.1140 -0.1140 Trans D: -0.0366 -0.0395 Lateral E: 0.3315 0.3310 Lateral F: 0.5345 0.5335 GALILS Commanded: 12500 -1600 5350 47050 -8800 -8400 Actual: 12500 -1600 5350 47050 -8800 -8400 SETMIR VALUES PrimDesOrient: 0.0 -59.3 -8.75 -512.73 1906.51 PrimOrient: 0.01 -59.26 -8.77 -512.68 1906.6 SECONDARY: ---------- Focus: 0.0000 Air temp: 12.17 Altitude: 30.000038956303893 MIGS TONIGHT NOMINAL Axial A: -9.4550 -9.4610 Axial B: -9.4670 -9.4760 Axial C: -9.4990 -9.5050 Trans D: 0.0930 0.0880 GALILS Commanded: 4633900 4627800 4651200 -50 -3450 Actual: 4607338 4607161 4607092 -50 -3450 SETMIR VALUES SecDesOrient: 3657.0 0.0 0.0 0.0 42.22 SecOrient: 3656.96 0.04 -0.07 -0.04 42.66 ---- Telescope Status ---- 02:24Z Started ventilation NA encl25m : open NA encl25m : closed No interlocks bypassed Status at: 0:31:41Z Telescope stowed at: 121.0, 29.9, -0.0 mount Instrument mounted: 19 Counterweights at: 509.6, 513.1, 509.8, 509.0 LN2 autofill systems: Connected and turned on 180L LN2 dewar scale: SP1 147.0 lbs, 22.0 psi ---- Software Used ---- -- STUI software: STUI : 1.7.13 alerts : 2.1.6 apo : 3.0.0 boss : 6.0.0 -boss.specMec : 3.0.4 guider : 4.0.0 ecamera : FAILED fliswarm : 0.1.1-alpha.0 hartmann : 2.0.0 hub : 5.0.0a0 mcp : 2.1 -mcp.plc : 34 -mcp.azFiduci : v1_146 -mcp.altFiduc : v1_146 -mcp.rotFiduc : v1_146 sop : 0.1.0-alpha.0 tcc : 1.4.0 apogee : not availble apogeecal : not availble apogeeql : v1_7_0dev STUIAdditions : origin/sdss5 -- done --
