= 20160523 Commissioning Plan =

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


-------------

== Twilight ==

Before Sunset at Az 155 (or Az 0) please  take twilight LRS2 and VIRUS exposures that have good flux (more than 10,000 ADU) but not saturated on either LRS2b, LRS2r, or VIRUS

-------------

== RA training at the start of the night ==

-------------

== On sky engineering tests: ==

=== Pointing zero points ===

Purpose:  We are testing a new pier model located at /opt/het/hetdex/etc/configfiles as structureModel.dat.   If you need to revert to the original please copy over structureModel.dat.orig.


Procedure:  
* Observe a somewhat bright (~10th mag) star at the center of track every 15 degrees in Az pointing to the IHMP.  You may skip Az 0 and Az 180.
* 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:

=== Dither Test ===

Procedure: 
*  Restack  
*  Select a rich globular cluster with a full trajectory
*  Using gstar2 Put the globular cluster in the center of the VIRUS IFU array 
*  Setup guiding on one guide probe but with a 2nd star (not guiding but saving images) in the second guide probe.
*  Observe the target for a full track taking short dithers of 60 seconds for each position.   Each dither set needs to be a separate observation.  Save an ACAM image after each set.  Save guider data from both guiders for the full trajectory.

== Closed dome or post-pointing test ==


Take long darks (same as long darks from regular calibrations, 10min I think...) with LRS2 with the ion pumps on, to measure the stray light associated with them
