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


== twilight 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: ==


=== Basic offsetting ===

 * Setup on a star a bit before center of track in the north but not at Az 0.
 * Start the trajectory
 * Try offsetting on the ACAM using normal telescope offsets
 * Try offsetting with the BIB using normal telescope offsets
 * Try offsetting with the GC using both normal telescope offsets and probe offsets
 * Try setting up on the WFS to make sure those normal mgp or lower level probe-offset commands work
 * If you get errors or clearly wrong offsets call Jason and report the specific problem.

=== Basic offsetting using the correction command ===
 
 * 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 '''position''' on the ACAM.
 * '''Guide on the BIB right in the center'''
 * Center the star very carefully in the center of the BIB.
 * '''Switch to guiding on the GC'''
 * Save a BIB image
 * Put in the ACAM and save an image with the ACAM
 * measure and record the position on the ACAM.
 * '''Check that our current LRS2-B -> LRS2-R offsets yield good centering.'''


=== 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
 * When making offsets make sure to use the new corrections box.
 * 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.

=== Center of track pointing zero points ===

Purpose:  we are testing a new pointing model.   

Procedure:  
* Observe a somewhat bright (~12th mag) star near the '''center''' 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:
