20170610 Commissioning Plan

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

Twilight:

blue sky PV images of the primary

Purpose: We will have a mirror swap on Monday so we want to get images of every primary mirror

Procedure:

• Point telescope and dome to north at twilight (this could be done during OPS when sun is low enough).
• Open to blue sky
• Set tracker position to center (0,0) and take a PV image being sure its not saturating but has good
  signal. If you see good signal ~190-200 this should be a good exposure time for the test.
• Turn PV pipeline off and run command pvtwilight in jove terminal window (you may leave start images on if
  if you would like to see the resulting images from the script).

Note that until the doors are back on VE1 we don't need LRS2 or VIRUS twilights or cals.

Night time engineering:

BIB Drag Test

• Make sure your stack is pretty good (RSE < 250)
• Make sure GROC is pretty well set
• Select a 13th mag target near the start of the track for all probes and targeted on BIB using shuffle
• Setup on BIB and start guiding on BIB at the center of the BIB field of view: 79 98
• Center up both guide probes and start metrology loops.
• Center up at least one OWFS and run it closed loop.
• set bib exposure to be not saturated but at least 3 seconds ( e.g. 2 seconds with 2 co-add)
• Record a time, GROC and RSE in the log
• Hit "store images" and "Start Metrology Loop" for GC1, GC2, WFS1, WFS2, TT, BIB
• In this test we should NEVER apply X,Y, or GROC offset corrections
• Run until the end of track
• when done, record a time, GROC and RSE in the log

Run this at several different Az. Priorities 40, 0, 320, 10, 350, 20, 340, 30, 330

Remaining Az: 10, 350, 20, 340, 30, 330

test vlexp dither script

Purpose: We have updated the dither script to run to see if we can move and keep the WFS centered while doing VIRUS dithered exposures. This requires VIRUS to be up and running.

Procedure:

• Setup on For VIRUS on IFU 095 for Globular cluster ngc6205 in the early in the track. (another very rich and big GC would be fine).
• Start guiding and close the loop on a WFS.
• Take a 180 second per dither set using $HET_SRC_ROOT/integration/hetdex-dither.py
• Take a 180 second per dither set using $HET_SRC_ROOT/integration/vlexp -i virus -dither -t tst -texp 180 -pobj vlexpdither
• Watch carefully as you dither to see if the position of the WFS gets much worse.
• repeat alternating between the two methods for the entire track.
• Report any problems.

Testing of the ACAM position

Purpose: We want to see if the ACAM position changes with respect to the IHMP over time. We want this data about 2 times per week and when ever we get an unusually high or low temperature.

Determine the Center of the BIB:

• Select a 14th mag star in a reasonably rich field with shuffle for the BIB
• Setup on the very center of the BIB field of view (79, 98) and save an image.
• Guide on one of the guide probes
• Put in the ACAM and save an shallow image with the target star not saturated.
• Report on the position of the BIB in the night report and on NightOperations/Commissioning/Results
• Save a deeper image which should show more than a dozen stars.

Determine the Center of LRS2-B

• Select a 14th mag star in a reasonably rich field with shuffle for the LRS2-B
• Setup on LRS2-B and start guiding on one of the guiders
• Take LRS2-B spectrum, probably 60 seconds.
• Adjust the position so that the star is at the center of LRS2-B IFU using lmap note there might be sign flips
• Confirm the star is at the center of the IFU by taking a spectrum.
• Once it is as the center of the IFU put in the ACAM and take a shallow image so that the star is not saturated.
• Report on the position of the LRS2-B in the night report and on NightOperations/Commissioning/Results
• Take a deeper image so that there are large number of stars.

Determine the Center of LRS2-R

• Select a 14th mag star in a reasonably rich field with shuffle for the LRS2-R
• Setup on LRS2-R and start guiding on one of the guiders
• Take LRS2-R spectrum, probably 60 seconds.
• Adjust the position so that the star is at the center of LRS2-R IFU using lmap
• Confirm the star is at the center of the IFU by taking a spectrum.
• Once it is as the center of the IFU put in the ACAM and take a shallow image so that the star is not saturated.
• Report on the position of the LRS2-R in the night report and on NightOperations/Commissioning/Results
• Take a deeper image so that there are large number of stars.

Repeat the above tests a few times at different Az to confirm that the positions are good.

Image quality tests

Purpose: The purpose of this test is to determine if there are any dome seeing constraints of the HET image quality. Thus this test should be done under good stable conditions, typically DIMM < 0.9" and not while the temperature is dropping, ie. the start of the night.

Procedure:

• Make sure conditions are stable and DIMM < 0.95.
• Select a target into the wind in the first half of the track. Use do_shuffle for all probes probably using the --use_brightness true option.
• Setup on the target on the ACAM and guide
• Set imagers with exposures of at least 5 seconds and WFS with exposures at least 15 seconds.
• Make sure metrology and images are being saved for 5 minutes.
• Pull out the ACAM and guide on the BIB with exposures of at least 5 seconds.
• Save images and data for 5 minutes.
• repeat the three steps above for most of the rest of the track.
• At the end of the test go to CCAS and take a post-observing measurement (you may not need to re-stack).

Testing Probe offsets

Purpose: We want to see how accurately we offset using probe offsets with the same tools that we used for the guide probe measurements.

Procedure:

• Setup on For VIRUS on IFU 095 for Globular cluster ngc6205 in the east early in the track.
• Setup on GC1 (You can also run a WFS to keep good IQ).
• Expose VIRUS for 180 seconds syscmd -v -V 'expose( seconds=180, x_binning=2, y_binning=1, type="sci", object="ngc6205_095_E", observation=2, exposure=1 )'
• Wait for the shutter to close syscmd -V 'wait_for_shutter_close(observation=2, exposure=1 )'
• Move to 2nd dither position with a probe offset move mgp -toff=-1.27,0.73
• Expose VIRUS for 180 seconds syscmd -v -V 'expose( seconds=180, x_binning=2, y_binning=1, type="sci", object="ngc6205_095_E", observation=2, exposure=2 )'
• Wait for the shutter to close syscmd -V 'wait_for_shutter_close(observation=2, exposure=1 )'
• Move to 3rd dither position with a probe offset move mgp -toff=0.0,-1.46
• Expose VIRUS for 180 seconds syscmd -v -V 'expose( seconds=180, x_binning=2, y_binning=1, type="sci", object="ngc6205_095_E", observation=2, exposure=3 )'
• Wait for the shutter to close syscmd -V 'wait_for_shutter_close(observation=2, exposure=3 )'
• Move back to the start with a probe offset move mgp -toff=1.27,0.73

• Repeat the test but guiding on GC2 Be sure to change the observation number to 3
• Repeat the test but guiding on GC1 Be sure to change the observation number to 4
• Repeat the test but guiding on GC2 Be sure to change the observation number to 5
