20161116 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 LRS2 upgrade and closed-loop focus testing

Lowest Priority: Science and HETDEX engineering

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.

twilights with VIRUS with different tracker positions

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

On-sky engineering:

Run full tracks with bib camera+

• Use do_shuffle to setup on a V=12 star near start of track555
• We must modify the usual do_shuffle run:

To get bib to setup use this line in fplane.txt
555     0.0   -70.0     900     900     900     0.0     1.0
Use the new script:   shuffle_config_matt3

When you have guide stars acquired, use this command to get final star centering on bib:
syscmd -T 'offset_trajectory(dx_ang=+5, dy_ang=+4, adjust_probes="true")'  

NOTE: Eventually we can modify the X,Y values in the fplane.txt file and eliminate this last offset_trajectory step. 
  I was going to do this, but at 3am I new I make a sign-change error and mess things up!

• Have TO focus up and have RA center at least one OWFS
• Use GUI in PAS to move star to bib and hold probes on their targets
• close focus loop
• set bib exposure to 2sec (for V=12 star)
• Record a time in the log
• Use TO save images button to save gc1,gc2.wf1,wf2 images
• Manual start saving bib images
• Run until the end of track
• when done, record a time in the log

VIRUS observations of Globular cluster

• Use do_shuffle to set up on (center) of a globular cluster
  • NOTE: NGC7006 start track at 2:01UT
• Have TO setup guiding on gc1 or gc2
• After RA sets up at least one OWFS, have TO close focus loop
• start saving bib images
• record start time in the log
• Run the VIRUS dither.py script
• stop saving bib images
• record end time in the log

Close-Loop Focus Tracks

• Set up on a foc09 star in the usual way (i.e. use do_shuffle or gstar to put the V=9 star in DWFS8 and guide stars in gc1,gc2).
• Set up wf1/wf2 in usual way
• Record time in log
• Have TO close focus loop
  • Check the DMI pipeline is running.
  • Start Metrology loop and activate loop on DMI.
  • Make sure OWFS that you want to guide focus on is well centered.
  • Start and then Activate the metrology loop on the OWFS that you would like to start guiding focus on.
• At end of track, record time
• After each track set, adjust GRoC

Niv and Jason have asked for a variety of structure AZ values, but we must stay away from AZ=64 (CCAS) as this is not implemented in the WFS pipeline yet.

TEST 5: ACAM focus (THIS NEEDS WORK BEFORE WE UNDERSTAND THIS TEST!)

• Insure that temperatures are stable and DIMM seeing is better than 1.5"
• Set up on geo-sat (probably GOES-14)
• Have TO focus on satellite image using dwfs8
• record a dw data dump to capture telescope focus
• insert the acq mirror and run /home/mcs/astronomer/scriptacq
• have TO refocus with dwfs8
• record a dw data dump to capture telescope focus (to determine if significant drift occurred)

Analysis: Measure width of PSF to get acq focus curve and measure focus offset (should be close to zero).

TEST 6: Dither test on DWFS9 in IFU 052

Purpose: We want to see the reproducibility of the dithers imaged through the DWFS9 point grey camera which might be in IFU052. Procedure:

• Put a really bright star on IFU052 to confirm that we can actually confirm that it is right one (you will need a guide star to hold it steady.
• If you can confirm that this is the right IFU slot try the following steps
  • Setup on a 14th mag star for IFU052
  • Guide on GC1 or GC2
  • make sure GROC < 400
  • make sure you are in dither position 1
  • take a few images with the point grey camera dwfs9
  • change to dither position 2 with syscmd -P -v 'AdjustDither(pos=2)'
  • take a few images with the point grey camera dwfs9
  • change to dither position 3 with syscmd -P -v 'AdjustDither(pos=3)'
  • take a few images with the point grey camera dwfs9
  • move back to dither position 1 and repeat the last 7 steps until you collect 3 cycles of data.

Drift test: GC1-GC2-ACQ

Purpose: We want to see how much drift there is from one side of the IHMP to the other. Generally we want to guide on one GC and watch the others. This should be done in the south. At this time (20161107) HL has requested that we collect at least 20 sets of data collected as we describe below.

Procedure:

• Get a good stack with good groc (GROC < 250).
• Record the GROC value and the truss temp.
• Setup for a full track with good focus
• Start saving images with GC1, GC2 and ACAM
• TO should maintain focus
• Be sure to run the DMI with 10 second interval.
• At the end of the test be sure to report the GROC value and final truss temp.

Science with LRS2-R and VIRUS Engineering (LOWEST PRIORITY)

Purpose: LRS2-R is available for beware of grouped targets with LRS2-B.

Procedure:

• NOTE: LRS2-R is in IFU slot 057
• You can use shuffle with the setup files from shuffle_config_matt or to try to compenstate for the new ACAM angles try shuffle_config_matt2
• Do a blind offset setup, ie. do_shuffle RA DEC 0 X 057 0 0 test
