+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: ==
+
+
+=== Closed dome trajectories ===
+
+Purpose:  Exercise the system to find any problems with the upgrades recently done to TMCS and TCS.
+
+Procedure:  
+ *  Send a trajectory from do_shuffle
+ *  Setup on trajectory, including moving all guide probes to position
+ *  Put one some light in the dome
+ *  Run all cameras.
+ *  Run pipelines for WFS
+ *  Make offsets on all guiders and ACAM.
+
+Repeat multiple times during the night as long as the weather does not allow you to open.
+
+
+== Twilight Tests ==
+
+ === start doing twilights with VIRUS with different tracker positions ===
+
+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, B filter)
+ *  When you hit the correct flux level (biased to a slight higher value) execute the specialtwilight script
+
+== 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.
+
+'''NOTE:  Due to the poor weather the emphasis should be on the Satellite calibrations so do several different satellites before moving on to the stars'''
+
+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)  '''NOTE:  This can be done one jove terminal as {{{startsaving}}} followed by {{{stopsaving}}}'''
+ *  offset to CWFS (-5.5 in X)
+ *  null out the offsets in X and Y only.
+        * The X and Y prescribed corrections are between -1 and 1.
+        * The Theta and Phi prescribed corrections are between -10 and 10.
+        * The Focus prescribed correction is between -0.05 and 0.05 
+ *  save 15 images with CWFS (use 3-5 sec exposures)
+ *  move back to DWFS8 (+5.5 in X)
+ *  repeat the above steps 2 more times
+
+'''Now we start on a normal star for Az 180, 234, 292, 335, 0'''
+
+ *  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
+       * The X and Y prescribed corrections are between -1 and 1.
+       * The Theta and Phi prescribed corrections are between -10 and 10.
+       * The Focus prescribed correction is between -0.05 and 0.05 
+ *  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 '''NOTE:  This can be done one jove terminal as {{{startsaving}}} followed by {{{stopsaving}}}'''
+ *  wait 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
+       * The X and Y prescribed corrections are between -1 and 1.
+       * The Theta and Phi prescribed corrections are between -10 and 10.
+       * The Focus prescribed correction is between -0.05 and 0.05 
+ *  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.
+ *  Close the PFIP shutter {{{ syscmd -P -v 'CloseShutter()' }}}
+
+Repeat test: going back to the geostationary satellite and then choosing a new star at the next Az in the list: 180, 234, 292, 335, 0.   
+
+'''NOTE:  If the geostationary satellite goes into eclipse then just skip those steps.'''
+
+
+
+ === doing globular clusters with VIRUS ===
+
+Purpose:  We need to fill the IFU with lots of stars.   Take a bright GC and move it to one position in the IFU array:  between slot 94 and 95.
+
+Procedure:
+ *  Select a bright globular cluster a little before center of track (try to avoid the CCAS tower).
+ *  Using do_shuffle put the center of the GC between IFU 95 and IFU 95.  This should be an offset of +50 in Y from IFU 095.  Double check with setup images.  If you can not get this to work then you can use gstar2.   
+ *  What ever method is used to setup on the the cluster, save the IHMP clearly in the RA logs.
+ *  setup on the target
+ *  save an ACAM image to document the setup.
+ *  go through a series of dithers with 360 second exposure at each dither.
+ *  contact Karl that the test is complete.
+
+=== 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.
