VIRUS Alignment Characterization Procedures
Goal
The goal is to take 5 unbinned Hg lamp exposures, 5 dark frames (with same PFIP exposure time), 5 unbinned Cd-A lamp exposures, 5 dark frames (with same PFIP exposure time), and 5 bias frames to test the alignment of newly installed VIRUS units once these units have been stable and cold for (at least) 16 hours. The Hg and Cd-A lamp exposures need 45-55k in the peak line on the target IFUs. The dark frames should be the same exposure times as the lamp PFIP shutter exposure times (not the FCU exposure time).
Note we are trying to use the same numbering for engineering tests so for the test exposures please use the 6000s and the final VAC exposures please use 7100-7199.
The VG and IP must be OFF while taking the data for this test.
Note exposure times for Hg and Cd-A need to be checked every time for new IFUs. Listed below are the exposure times from previous dates/units.
Reporting
When you have completed a successful set of VAC, email astronomer@, Phillip, and Renny.
- The email subject line should include 'VAC' and the V-number in the format 'Vnnn'
- The email body should include:
- the yyyymmdd of the data directory
- the observation numbers for each of the bias, Hg, and Cd data. These should be:
- 7101 for Hg
- 7102 for Cd
- 7103 for Bias

New script (testing mode for now)
Run ~sir/dev/astro/operations/virus_tests.sh <vac|dsf> [-skipip]
"skipip" only if you do not need that script deal with IP and VG.
Script first warm up lamps and entering test mode to determine correct exposure time. It will ask for max flux level after each test exposure and will display corrected exposure time. Type "next" when happy with exp time and script will ask run exposure or not. In case of "n" answer it just display correct command to run
Here is an example VAC run

Scripted commands
Note about testing exposure times:
- In testing that the brightest arc line is in the range 45-55K, just replace "-L 5" with "-L 1" in the script commands below so that you take a single image at a time.
Note on naming scheme:
- for binning 1x1 name will be "unbinned_<lamp name>"
- for all other non standard binning scheme are : "<lamp name>_<binning>"
Commands (it's recommended to run each command with "--dry-run" first for checking):
First step is to determine appropriate exp time for Hg and Cd-A to get 45-55k in the peak line on the target IFUs. Do this using observation numbers 6XXX and start with exposure times about half of those given above in case you saturate.
Try the following for faster work:
Turn on the Cd-A and Hg lamps through the TCS gui
ipvg off -V
countdowns 780
Cd-A test exp vlcal -i virus --binning 1x1 -l cd-a -L 1 -bexp 55 -o 6101 -skip_warmup -B
Re-Turn on the Cd-A lamp and calculate the correct exposure time for the VIRUS unit of interest to get 50k peak.
Hg vlcal -i virus --binning 1x1 -l hg -L 1 -bexp 7 -o 6102 -skip_warmup -B
Re-Turn on the Hg lamp and calculate the correct exposure time for the VIRUS unit of interest to get 50k peak.
Now run the following but remembering to change the exposure times!!!
- vlcal -i virus --binning 1x1 -b 5 -o 7100 -skip_warmup -B
- vlcal -i virus --binning 1x1 -l cd-a -L 5 -bexp 20 -o 7101 -skip_warmup -B
- vlcal -i virus --binning 1x1 -l hg -L 5 -bexp 9 -o 7102 -skip_warmup -B
- ipvg on -V
Two scenarios: (assuming these are done in the day time)
- data taken with dark dome
- ipvg off -V
- biases vlcal -i virus --binning 1x1 -b 5 -o 7100
- Hg vlcal -i virus --binning 1x1 -l hg -L 5 -bexp 2.5 -o 7101
- Cd-A vlcal -i virus --binning 1x1 -l cd-a -L 5 -bexp 20 -o 7102
- ipvg on -V
- data taken with dome lights on
- ipvg off -V
- biases vlcal -i virus --binning 1x1 -b 5 -o 7100
- Hg vlcal -i virus --binning 1x1 -l hg -L 1 -bexp 2.5 -o 7101
- Cd-A vlcal -i virus --binning 1x1 -l cd-a -L 5 -bexp 30 -o 7102
- darks vlcal -i virus --binning 1x1 -d 5 -de 20 -o 7103
- darks vlcal -i virus --binning 1x1 -d 5 -de 45 -o 7104
- ipvg on -V
To judge the image flux levels
Use the virusview command to view the images from all 4 amps of a given S###. Measure the peak flux in each amp using the ds9 Scale histogram (Scale Parameters). Use the most sensitive amp to judge the max peak level. Use this level to estimate the exposure time needed to achieve a peak of 50K or so.
Low level commands
To take the bias frames one could do the following:
syscmd -V 'expose(seconds=0, x_binning=1, y_binning=1, type="zro", object="unbinned_bias", observation=7100, exposure=1 )' syscmd -V 'wait_for_write(observation=7100,exposure=1)' syscmd -V 'expose(seconds=0, x_binning=1, y_binning=1, type="zro", object="unbinned_bias", observation=7100, exposure=2 )' syscmd -V 'wait_for_write(observation=7100,exposure=2)' syscmd -V 'expose(seconds=0, x_binning=1, y_binning=1, type="zro", object="unbinned_bias", observation=7100, exposure=3 )' syscmd -V 'wait_for_write(observation=7100,exposure=3)' syscmd -V 'expose(seconds=0, x_binning=1, y_binning=1, type="zro", object="unbinned_bias", observation=7100, exposure=4 )' syscmd -V 'wait_for_write(observation=7100,exposure=4)' syscmd -V 'expose(seconds=0, x_binning=1, y_binning=1, type="zro", object="unbinned_bias", observation=7100, exposure=5 )' syscmd -V 'wait_for_write(observation=7100,exposure=5)'
Now take the lamp exposures (Note that the exposure time of 8.8 seconds has previously worked well for the brightest emission line for the S105 unit but might not be good for future units Try taking a test exposure with observation=6xxx.
Also note that the flux level of the Hg lamp does not fully stabilize until 13 minutes after it has been turned on.
ipvg off -V syscmd -P 'FCUDeployHead()' syscmd -P 'FCUEnableLamps(lamps="Hg",slider="a",state="on")' sleep 180 syscmd -P 'FCUExposeSliderA(time=0.1,lamp_name="Hg",headpos="overide",light_guide="blue",shutter="virus")' syscmd -V 'expose(seconds=20, x_binning=1, y_binning=1, type="cmp", object="unbinned_Hg", observation=7101, exposure=1 )' syscmd -P 'FCUExposeSliderA(time=8.0,lamp_name="Hg",headpos="overide",light_guide="blue",shutter="virus")' syscmd -V 'wait_for_write(observation=7101,exposure=1)' syscmd -V 'expose(seconds=20, x_binning=1, y_binning=1, type="cmp", object="unbinned_Hg", observation=7101, exposure=2 )' syscmd -P 'FCUExposeSliderA(time=8.0,lamp_name="Hg",headpos="overide",light_guide="blue",shutter="virus")' syscmd -V 'wait_for_write(observation=7101,exposure=2)' syscmd -V 'expose(seconds=20, x_binning=1, y_binning=1, type="cmp", object="unbinned_Hg", observation=7101, exposure=3 )' syscmd -P 'FCUExposeSliderA(time=8.0,lamp_name="Hg",headpos="overide",light_guide="blue",shutter="virus")' syscmd -V 'wait_for_write(observation=7101,exposure=3)' syscmd -V 'expose(seconds=20, x_binning=1, y_binning=1, type="cmp", object="unbinned_Hg", observation=7101, exposure=4 )' syscmd -P 'FCUExposeSliderA(time=8.0,lamp_name="Hg",headpos="overide",light_guide="blue",shutter="virus")' syscmd -V 'wait_for_write(observation=7101,exposure=4)' syscmd -V 'expose(seconds=20, x_binning=1, y_binning=1, type="cmp", object="unbinned_Hg", observation=7101, exposure=5 )' syscmd -P 'FCUExposeSliderA(time=8.0,lamp_name="Hg",headpos="overide",light_guide="blue",shutter="virus")' syscmd -V 'wait_for_write(observation=7101,exposure=5)' syscmd -P 'FCUEnableLamps(lamps="Hg",slider="a",state="off")' syscmd -P 'FCURetractHead()'
To take the dark frames: (at the PFIP exposure time)
syscmd -V 'expose(seconds=20, x_binning=1, y_binning=1, type="drk", object="unbinned_dark", observation=7102, exposure=1, dark="true" )' syscmd -V 'wait_for_write(observation=7102,exposure=1)' syscmd -V 'expose(seconds=20, x_binning=1, y_binning=1, type="drk", object="unbinned_dark", observation=7102, exposure=2, dark="true" )' syscmd -V 'wait_for_write(observation=7102,exposure=2)' syscmd -V 'expose(seconds=20, x_binning=1, y_binning=1, type="drk", object="unbinned_dark", observation=7102, exposure=3, dark="true" )' syscmd -V 'wait_for_write(observation=7102,exposure=3)' syscmd -V 'expose(seconds=20, x_binning=1, y_binning=1, type="drk", object="unbinned_dark", observation=7102, exposure=4, dark="true" )' syscmd -V 'wait_for_write(observation=7102,exposure=4)' syscmd -V 'expose(seconds=20, x_binning=1, y_binning=1, type="drk", object="unbinned_dark", observation=7102, exposure=5, dark="true" )' syscmd -V 'wait_for_write(observation=7102,exposure=5)'
Then do the same for the Cd-A lamps
