20170407 Commissioning Plan

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

twilights tests

Test of HET Pupil with PV and CWFS

Procedure:

• Take a few PV and
• Take a few CWFS images
• Report to het-operations that these have been taken.

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:

Basic pointing tests

• Choose a very bright star with htopx near center of the track.
• Send to IHMP position with shuffle
• Move to star and check if pointing is pretty good (within 20")
• If you have pointing problems call Jason.

Basic offsetting using the correction command

• Call Randy so that he can come up for this test
• Setup on a star a bit before center of track in the north but not at Az 0.
• Start the trajectory
• Save an ACAM image
• Offset using the mouse clicks and try selecting the "Correction" option.
• The goal is to move the star from the position it starts at to the goal position, e.g. IHMP.
• Take an ACAM image
• Compare the RA and DEC in the headers. These should be identical.

Check fundamental positions

Purpose: The goal is to make sure that the fundamental positions LRS2-B, LRS2-R and BIB have not moved on the ACAM after the PFIP work.

Procedure:

• Setup on a 15th mag star on the LRS2-R on the ACAM.
• Save an ACAM imamge
• Take a LRS2 image and use lmap to determine centering.
• Report positions in the night report.
• Setup on a 15th mag star on the LRS2-B on the ACAM.
• Save an ACAM imamge
• Take a LRS2 image and use lmap to determine centering.
• report positions in the night report.
• Setup on a 15th mag star on the BIB on the ACAM.
• Center the star very carefully in the center of the BIB.
• Save a BIB image
• Put in the ACAM and save an image with the ACAM
• measure and record the position on the ACAM.

Pointing zero points

Purpose: we are testing a new pointing model. If you see a fundamental large error in the first test please call Matthew first then perhaps Niv so they can check to see if there is a sign error.

Procedure:

• Observe a somewhat bright (~12th mag) star near the start of the track every 10 degrees in Az pointing to the IHMP.
• Make sure that tip-tilt is running and that you are in focus.
• Save an image with ACAM with a exposure of at least 5 seconds and record the star position (x,y in pixels) in the night log along with the Az, tracker X and tracker Y. See the following example:

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 targetted on BIB using shuffle and shuffle_config_matt4
• Setup on BIB and start guiding on BIB.
• Center up both guide probes and start metrology loops.
• Center up at least one OWFS to watch focus.
• 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 320, 40, 350, 10, 0, 20, 340, 30, 330.
