Subject: 2.5m obslog 20210217 (SJD 59263) From: kpan@apo.nmsu.edu Date: Thu, 18 Feb 2021 11:47:00 +0000 (UTC) APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday February 17, 2021 (SJD 59263) ---- Observing Team ---- Christian Carter Kaike Pan ---- Observing Plan ---- Wed 17 FEB 2021 59263.0 0.36 01:47 12:34 04:36 15:26 ---- KK MWM until 06:35 ( 4.8 h), then BHM ( 6.0 h) ---- Observing Summary ---- High humidity all night long, radar and precipitation at times. BHM lost 10.6. Notes: ===== (1) /dev/vdd 688G 611G 77G 89% /home /dev/vdc1 11T 11T 676G 94% /data (2) We ran a few more overshoot tests. We witnessed both MOVE and GOTO_POS_VA MCP commands produce overshoot slews. (3) We shoveled the entire apron, the walkway to the Ops building, and cart bay area. ---- Observing Log ---- ============================================================================ Afternoon Checkout ============================================================================ Tested actors. Exercised manipulator arm. motorPosition sp1: -629, -608, -573; ---------- Median spectrographs temperatures: Tsp1= 1.6 Outside air temperature= -6.5; No BOSS focus ring adjustments. Mirror numbers are in spec. High humidity on site with with more cold temperatures and precipitation in the forecast. Did not begin ventilation. ============================================================================ Night ============================================================================ We ran a few more tests with MCP commands MOVE and GOTO_POS_VA. We found that both MOVE and GOTO_POS_VA at times produce overshoots and at times do not. Neither one appears to reliably avoid overshoots. GOTO_POS_VA tends to produce overshoots (with this particular procedure) but does not produce one every single time. MOVE at times does and at times does not result in overshoots. (1) Attempt to produce overshoot with regular procedure: at 121,30,00 to begin with tcc axis init tcc track 121,31 mount /rota=0 /rotty=mount tcc axis stop tcc axis init tcc track 121,30 mount /rota=0 /rotty=mount "Tracking" SEM STEAL MCP 'Move' Button, ALT=10 Slew ends at ALT=10. Expected overshoot; no overshoot. (2) Ran the exact same test again. at 121,30,00 to begin with tcc axis init tcc track 121,31 mount /rota=0 /rotty=mount tcc axis stop tcc axis init tcc track 121,30 mount /rota=0 /rotty=mount "Tracking" SEM STEAL MCP 'Move' Button, ALT=10 Slew ends at ALT=9. Overshoot. The exact same procedure twice in succession produced two different results. (3) What about the MOVE command? at 121,30,00 to begin with tcc axis init tcc track 121,31 mount /rota=0 /rotty=mount tcc axis stop tcc axis init tcc track 121,30 mount /rota=0 /rotty=mount "Tracking" SEM STEAL ALT MOVE 10 Slew ends at ALT=10. No overshoot. (3) Is this behavior repeatable? at 121,30,00 to begin with tcc axis init tcc track 121,31 mount /rota=0 /rotty=mount tcc axis stop tcc axis init tcc track 121,30 mount /rota=0 /rotty=mount "Tracking" SEM STEAL ALT MOVE 10 Slew ends at ALT=9. Overshoot. The exact same procedure twice in succession produced two different results. 11:50Z: started morning calibration. ---- BOSS Spectrograph Collimation Summary ---- Afternoon Checkout Hartmanns: --- Focus --- Time Cart Scale M1 M2 Focus Az Alt Temp Wind Dir FWHM ================================================================================ 22:33 2-15002A 0.0 0 3659 0 121.0 30.1 -6.1 13 275 2.4 23:11 2-15002A 0.0 0 3658 0 121.0 30.1 -6.2 4 286 2.4 23:07:46 boss exposure 4.0, file=325467 23:08:56 boss exposure 4.0, file=325468 23:10:20 sp1.motor.move= 1159, 1158, 1158 23:10:20 Hartmann collimate output on cart #2 sp1: offset: r= 329 (In Focus); b= -6.2 (Out of focus) sp1: pred. move: spAverageMove= 1160 sp1: pred. resid: r= -831, b= -2.6, txt= OK, spTemp = 1.6 ---- Mirror Numbers ---- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A: -4.9270 -4.9280 Axial B: -4.6680 -4.6660 Axial C: -5.7760 -5.7770 Trans D: -4.3730 -4.3890 Lateral E: 0.3750 0.3750 Lateral F: 0.5715 0.5675 GALILS Commanded: 5850 -4500 14850 28200 25200 24900 Actual: 5850 -4500 14850 28200 25200 24900 SETMIR VALUES PrimDesOrient: 0.0 69.89 100.0 375.3 622.11 PrimOrient: 0.04 69.89 100.0 375.3 622.11 SECONDARY: ---------- Focus: 0.0000 Air temp: -6.50 Altitude: 30.000038956303893 MIGS TONIGHT NOMINAL Axial A: -9.4440 -9.4420 Axial B: -9.4110 -9.4070 Axial C: -9.4940 -9.4960 Trans D: 0.0480 0.0420 GALILS Commanded: 4630150 4618100 4684600 -2000 -6600 Actual: 4605423 4586973 4633782 -2000 -6600 SETMIR VALUES SecDesOrient: 3657.0 -14.01 -2.9 12.5 114.22 SecOrient: 3658.12 -14.09 -2.95 12.66 114.26 ---- Telescope Offsets and Scale ---- --- Offsets --- (arcsec) Time Cart Az Alt Rot objOff guideRot calibOff guideRMS ================================================================================ 11:11 2-15002A 121.0 30.0 0.0 (0.0,0.0) 0.0 ( 0, 0, 0) 99.999 ---- Focus Log ---- --- Focus --- Time Cart Scale M1 M2 Focus Az Alt Temp Wind Dir FWHM ================================================================================ 11:11 2-15002A 0.0 0 3657 0 121.0 30.0 -8.4 7 198 2.4 ---- Telescope Status ---- Did not open.
