June AuxTel Run Plan

We currently have an AuxTel engineering run scheduled for June 10-13. There will be non-MOSS observations that need to be taken, but we should be able to take at least several hours of data on all three nights, weather permitting.

Run Plan

1. For the three nights, we will vent (listed in priority order):
   1. not at all until we go on-sky
   2. starting early in the morning
   3. starting at 2pm
2. The observing plan is (for evening twilight start, go from redder to bluer bands for imaging to minimize sky background levels. In morning twilight go bluer to redder):
   1. start taking MOSS data as soon as 2 sec integrations in g band have under 10,000 ADU of sky background, when pointing at MOSS. Then run sequential MOSS collections until  
   2. sweep up and then down in elevation, taking 30 sec triplets at each elevation, in the i band. good choices are elevations of 80, 50, 40, 30 degrees. 
   3. take ~100 images with MOSS in g band
   4. repeat (a) in the r band
   5. take ~100 images with MOSS in g band
   6. repeat (a) in the g band
   7. take ~100 images with MOSS in g band
   8. iterate. 

AuxTel Note: 

• The available filters are ['empty_1', 'SDSSg_65mm', 'SDSSr_65mm', 'SDSSz_65mm']
   and gratings are ['empty_1', 'blue300lpmm_qn1', 'SDSSy_65mm', 'holo4_003']

Daytime Engineering possibilities: 

see if the spots from MOSS can be placed in a line at constant y. Then try stuttered imaging with faster pulse rep rate to get multiple measurements per CCD readout. 
This would also work with two spots on upper half and two on lower half, set up as a rectangle: 

To do

• Find offset between dome and MOSS
• make sure we know what filters are available in disperser and filter wheels. Take images in all filters.
  • The available filters are ['empty_1', 'SDSSg_65mm', 'SDSSr_65mm', 'SDSSz_65mm']
     and gratings are ['empty_1', 'blue300lpmm_qn1', 'SDSSy_65mm', 'holo4_003']
• write block script to take MOSS data based after an on-sky image and then return to the previous position (so turn off dome following, go to MOSS, take images, turn dome following back on)
• test the MOSS block script before the engineering run during the day
• write block script to take elevation sweep data in g, r, i bands
• test the elevation sweep block script on one of the test stands
