20161218 Commissioning Plan

Priorities for test are in the order listed in the plan below.

NOTE: The DMI should now be run for every trajectory with a 10 second cycle time.

Highest Priority: Engineering; do any support for WFS commissioning and parallel script testing.

Lowest Priority: Science Targets in dark/grey time.

twilights tests

VIRUS special twilights

Purpose: There is some interest in seeing what the long term illumination correction changes look like including what different track positions do to them. The script is "specialtwilight" in /home/mcs/astronomer/bin/. It takes a single argument which is the Observation number.

Procedure:

• Setup the guide camera for sky twilight (GC2, 0.1 sec exposure, B filter)
• When you hit the correct flux level (biased to a slight higher value, perhaps 5k) execute the specialtwilight script

Night time engineering:

CWFS+WFS Loop Control Tests

• Make sure your stack is pretty good (RSE < 250)
• Make sure GROC is pretty well set
• Select a 12th mag target near the start of the track for all probes and targetted on IHMP using shuffle and shuffle_config_matt4
• Setup on IHMP
• Center up both guide probes and start guiding on one of the guiders
• Set Exposure times for CWFS, WFS1 and WFS2 to about 5 seconds to assist in centering.
• Offset to CWFS using syscmd -T 'offset_trajectory(dx_ang=-5.5, dy_ang=0.0, adjust_probes="true")'
• Tweak up the position on the IHMP using further offset_trajectory commands.
• Center up both WFS using mgp -grid or mgp -poff. See mgp --help. This requires "Process Images" to be checked.
• Null out focus on WFS1. NOTE: WFS1 seems to perform better than WFS2 at the edges of the track
• Start metrology loop and Activate the loop on WFS1.
• Increase the exposure time for the CWFS, WFS1 and WFS2 to greater than 20 seconds for data taking.
• Hit "store images" and "Start Metrology Loop" for GC1, GC2, WFS1, WFS2, TT, CWFS, DMI (although there are no images for DMI)
• Run until the end of the track.

Run full tracks with bib camera+ to assess centroid drag

• Make sure your stack is pretty good (RSE < 250)
• Make sure GROC is pretty well set
• Use do_shuffle to setup on a V=12 star at BIB (position 555 in shuffle) near start of track
• Have TO focus up and have RA center at least one OWFS (preferably OWFS1 since that seems to work better).
• Use GUI in PAS to move star to bib and hold probes on their targets
• once focused close the loop on the WFS.
• set bib exposure to 2sec (for V=12 star)
• Record a time in the log
• Hit "store images" and "Start Metrology Loop" for GC1, GC2, WFS1, WFS2, TT, CWFS, DMI (although there are no images for DMI)
• In this test we should NEVER apply X,Y, or GROC offset corrections
• Run until the end of track
• when done, record a time in the log

Test Parallel Science script

• Start a trajectory
• execute $HET_SRC_ROOT/integration/parallel-exposure.py --help to see the parameters for the new script example $HET_SRC_ROOT/integration/parallel-exposure.py -p lrs2 -t sci -i 230 -N testtarget -n parallel -O 3 -E 1 -o 2 -e 1
• take an exposure of several minutes long
• look at the logs for VIRUS and LRS2 and record any ERRORS
• look at the headers of the LRS2 and VIRUS fits files to see what was not populated
• look at the fits images to see if things look normal.

Optimize LRS2-B to LRS2-R offsets

• Start a trajectory
• setup on ACAM and one guide probe at the LRS2-B location.
• offset from LRS2-B to LRS2-R using: B2R: syscmd -T 'offset_trajectory(dx_ang=-101, dy_ang=+4, adjust_probes="true")'
  • Guider should stay in Active mode
  • Allow guider to catch the star and drag to the final position
• once the guider has settled to position measure the position on ACAM
• adjust the dx_ang and dy_ang until you can move from the two locations at will.
• update the wiki with the new offset distances and send an e-mail with new values to het-operations
• ask Sergey to update mpg

Science with LRS2 or VIRUS

• Select targets based on Priority and to a lesser extent modified priority
• Try to use WFS1 during science targets if possible NOTE: Probably not possible for LRS2-B -> LRS2-R sequence tests.
• Save PSU17-1-002 and PSU17-1-005 for times when other high priority targets can't be done, ie. those programs have targets at all times of the night.
• For the first half of the night:
  • Do M17-1-001 in the only south track at the start of the night P0 visits then P1
  • Do UT17-1-015 during dark time until P1 done
  • Split gray time between UT17-1-011 and UT17-1-014 until P1 done NOTE: For UT17-1-011 the PI put in their secondary preference in the tenths column of the priority, e.g. 1.0 higher priority than 1.1.

Closed dome engineering for bad weather, or while stacking:

Long VIRUS darks

Purpose: In each RA run take 10 x 6 minute dark with a dark dome with VIRUS. Report this in the RA report and send e-mail to Karl that this has been done.

Closed dome trajectories

Purpose: Exercise the system to find any problems with the upgrades recently done to TMCS and TCS.

Procedure:

• Send a trajectory from do_shuffle
• Setup on trajectory, including moving all guide probes to position
• Put on some light in the dome
• Run all cameras.
• Run WFS1 and WFS2 with processing enabled.
• Make offsets on all guiders and ACAM.

Repeat multiple times during the night as long as the weather does not allow you to open. Report any problems with shuffle or TCS.
