This code, and the sisters acm_dark_* codes, take bias and dark frames with the acm on HET. The routines that take the images (acm_bias_take and acm_dark_take) run only on mcs (as of Jan2018). The routines that the user usually uses are: acm_bias_run and acm_dark_run:
% # take 40 acm bias frames % acm_bias_run 40 % # take 40 acm 10sec dark frames % acm_dark_run 40 10 NOTE: only 5,10,20 second dark frames are currently handled.These are actually fairly klugy routine written on mcs during cloudy weather. Some upgrades would be desirable, but these are better than nothing. The bias level for acm is approximately BIAS = 1381.0 adu. Using acm_bias_run for just a few images can help you determine if extraneous light sources (PV cam, etc,,,,) are on in the HET system.
Below I include some notes I made on mcs during the early development of these routines.

The second is the mean error, and the third is the 1-sigma error per pixel. All values are in adu. Finally the image base name is given for each bias frame. On 20180107 I installed this in: /home/mcs/sco/Installs/install_mcs_20171129/bin/bini/ I also place a copy in acm_scripts on buckaroo I also write some dark scripts: [astronomer@mcs acm_scripts]$ acm_dark_take 20 [astronomer@mcs acm_scripts]$ acm_bias_check N 1386.0487 0.1235 80.3717 25 20180107T091020.8_acm_sci Note that the only exposure tiems recognized are: 5, 10, 20 To make multiple runs: [astronomer@mcs acm_scripts]$ acm_dark_run 3 5 1383.1637 0.0548 35.6544 25 20180107T091625.7_acm_sci 1383.0903 0.0539 35.0739 25 20180107T091640.0_acm_sci 1383.3611 0.0544 35.4222 25 20180107T091654.2_acm_sci To run 3 5sec darks and write the output to a file named "list.dark5": [astronomer@mcs acm_scripts]$ acm_dark_run 3 5 | tee -a list.dark5
Matt modified his script11 and created the new script named "getACMcals". It still hard codes the number of images taken, but some very useful commands were added to the top of the script:
[astronomer@mcs ~]$ head getACMcals syscmd -P 'PowerPV_CWFSCamera(state="false")' syscmd -P 'FCUDeployHead()' syscmd -P 'RetractACQCameraMirror(state="true")' syscmd -p 'ACQ_SetIntervalSpeed(speed=5)' syscmd -p 'ACQ_SetExposureTime(time=0.01)' syscmd -p 'ACQ_CyclePipeline(procMode="none",imageFilename="")'I need to add these commands to acm_bias_take and acm_dark_take.
