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


== twilight tests ==

=== Standard LRS2 twilight for any science frames that might be 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: ==


=== 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
 * 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 40, 0, 20, 340, 30, 330.

Az already done:
 * 350, 10, 320 on 20170415

=== Prep for science ===

 * Check LRS2-B and LRS2-R positions on ACAM
 * Check offset from LRS2-B to LRS2-R with mpg
 * check VIRUS dither exposures for HETDEX fields

== Closed dome engineering for bad weather, or while stacking: ==

Full set of LRS2 and VIRUS cals.

Special cals that need to be done:
  * LRS2 {{{FeAr}}} 1800s blue x4 
  * VIRUS 10 darks of 360 seconds

See and update [https://hettrac:8001/trac/WFUCommissioning/wiki/NightOperations/SciencePlans/longcals longcals] when done.
