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

Highest Priority:   Engineering; do any support for Hanshin or Randy in support of Hanshin.   

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

=== Single calibration with both VIRUS and LRS ===

Purpose:  Jason would like us to get a single bias, a single dark, a single line lamp and a single flat for both LRS and VIRUS tonight.

=== VIRUS DARKS ===

Purpose:  Karl would like to get 20 x 6 minute darks some time over the next few nights.  This only needs to be done once.

=== VIRUS FLATS ===

Purpose:  Karl would like to get 10 ldls flats some time over the next few nights.   This only needs to be done once.


== Twilight Tests ==

 None tonight.   We will need to restart these tomorrow night.

== On-sky engineering: ==

 === Calibration of CWFS ===

Purpose:  We want to calibrate the CWFS using DWFS8 on a geostationary satellite and OWFS using DWFS8 on a star for a full trajectory.

Procedure:  
 *  setup on a geostationary satellite on the IHMP position
 *  get rough focus and confirm that GROC is ok
 *  Retract ACAM
 *  Open the PFIP shutter {{{ syscmd -P -v 'OpenShutter()' }}}
 *  null out the offsets for X,Y,focus, theta, phi on DWFS8
 *  save 15 images with DWFS8 ( use 3-4 sec exposures)
 *  offset to CWFS (-5.5 in X and -1 in Y)
 *  null out the offsets in X and Y only.
 *  save 15 images with CWFS (use 3-5 sec exposures)
 *  repeat the above steps 2 more times

'''Now we start on a normal star'''

 *  setup on an 11 mag star on the IHMP
 *  move all 4 guide probes to the correct RA and DEC positions from gstar or shuffle.
 *  save probe positions in the RA log with /home/mcs/astronomer/caldwell/shoprobes
 *  move the guide probes so that the guide stars are well centered
 *  guide with either GC1 or GC2
 *  get decent focus and then check and correct any GROC
 *  Retract ACAM
 *  Open the PFIP shutter {{{ syscmd -P -v 'OpenShutter()' }}}
 *  null out the X, Y, Focus, Theta, Phi from DWFS8 
       *  To make X or Y offsets you will need to:
             *  open the loop on the guider
             *  make your offset with the handpaddle
             *  clear the fiducial
             *  watch as new fiducials are set to see if it looks good
             *  close the loop on the guider
       * To make the Theta and Phi offsets you will need to:
             *  open the loop on the TTC
             *  make your offset with the handpaddle
             *  clear the fiducial
             *  watch as new fiducials are set to see if it looks good
             *  close the loop on the TTC
 *  make small offsets with the OWFS1 and OWFS2 to get the lenslet centered.

{{{
To move the wfs probes:
syscmd -T -v 'WFS1_offset_probe( dx_ang=1.0, dy_ang=0.0) '
syscmd -T -v 'WFS2_offset_probe( dx_ang=0.0, dy_ang=-0.5) '
The coordinates are in units of arcseconds.
}}}

 *  save probe positions in the RA log with /home/mcs/astronomer/caldwell/shoprobes
 *  save at least 15 images (at the same time) with all cameras that are running:  GC1, GC2, WFS1, WFS2, DWFS8, TT
 *  10 minutes
 *  null out corrections on DWFS8
       * NOTE:   if you need to make X and Y offsets you should probably do this with a trajectory offset with probes=true to keep the WFS1 and WFS2 well centered
       * e.g.  {{{ syscmd -T 'offset_trajectory(dx_ang=0.0, dy_ang=-0.3, adjust_probes="true")' }}}
 *  check GROC, make correction is required ( > 500 um correction)
 *  null out corrections on WFS8 again if required
 *  save at least 15 images (at the same time) with all cameras that are running:  GC1, GC2, WFS1, WFS2, DWFS8, TT
 *  repeat the last 5 steps until the end of the track.

Repeat test: going back to the geostationary satellite and then choosing a star 40 degrees away in Az from the last Az.



=== Test offsetting from LRS2-B -> R using GC1 & ACAM as a function or rho angle ===

Purpose:  We want to see if rho angle of the tracker matters for making good reproducible offsets from LRS2-B to LRS2-R.

Procedure: 
 *  Setup on a Az = 0 star (not saturated so probably should use V=16) using GC1 and LRS2-B near the start of the track
 *  Setup on one of the GC in nearly exactly the center of the GC field (record the pixel X and Y used)
 *  Be sure to record the tracker positions including the rho angle
 *  Using repeated offsets from LRS2-B to LRS2-R positions (but only looking at the ACAM images) determine the best value to use for the offset
 *  Repeat the 4 steps above but Az=0 stars near the center and the end of the trajectory.


 === Test offsetting from LRS2-B -> R using GC1 & ACAM as a function of Az ===

Purpose:  We want to see if the Az matters for making good reproducible offsets from LRS2-B to LRS2-R.

Procedure: 
 *  Setup on a star (not saturated so probably should use V=16) using GC1 and LRS2-B
 *  Setup on one of the GC in nearly exactly the center of the GC field (record the pixel X and Y used)
 *  Using repeated offsets from LRS2-B to LRS2-R positions (but only looking at the ACAM images) determine the best value to use for the offset
 *  Repeat this test for several every 40 degrees of Az.
