This wiki page is a guide to use the Differential Image Motion Sensor Using Multiapertures (DIMSUM) instrumentation that was installed to Aux Tel between December 6th and 16th. I am currently writing this as a wiki page to be able to get feedback during the process of documentation. Once everything is finalized I can create a pdf file if requested.

The SMA threads are 1/4-36. Digikey sells them, part number A104989-ND. Bought 100 of them.
Asked Helen to place this order since credit card failed.

Changed optical fiber configuration to have Xenon source feed attenuator module to 600- micron 1:4 fiber then 4 of 200 micron 1:4 bundles. This gives us 16 sources 200 microns in diameter.
I did find one fiber that was flopping/loose in the pegboard, that was presumably the one that showed anomalous behavior in analysis done Feb 2024 by Ali K.
Checked using headlamp that all fibers look comparable.
When running remotely on data collection using gphoto-2 to interrogate aperture worked fine, after power cycling the camera.
But the
./CommunicateTrial.sh
script failed.

After Slack messaging with Ali have turned off live mode in EOS utility.
Tried CU2A5984.CR2. no sources.
Ali suggests running this program:
#! /bin/bash
gphoto2 --reset
gphoto2 --auto-detect --set-config /main/imgsettings/imageformat=32
gphoto2 --set-config /main/actions/eosremoterelease='5'
gphoto2 --set-config /main/actions/cancelautofocus='0'
gphoto2 --set-config capturetarget='1'
gphoto2 --capture-image-and-download --no-keep
got:
(base) stubbslab@MacBook-Stubbs code % source ./testprogram.sh

so it took four images, 5985 to 5988.

That worked!
