• Wrote a script in the weekend to transfer initially internally written files to an external disk while keep taking data. It takes four arguments, path/to/source (where the files are internally saved), path/to/target (the directory of the external disk), file type, number of files to transfer after. That would let us write the files into the internal disk and transfer them over while keep taking more data and never run out of local memory. The video below is a demonstration with a threshold of 50 files. I wrote a dummy bash script to create files with increasing numbers and wrote it to a directory:

• There was a mild earthquake during the weekend. Nothing significant happened to the setup.
• We further stabilized the pegboard. It still moves but is not completely like a sail.
• Added additional sources by adding 1 to 4 optical fibers to the ends of 1 to 7 optical fibers. Some of the 1 to 4 optical fibers did not work anymore.
• We technically should be able to get 18 sources. However, while some sources after being divided the 4 are sufficiently bright, others could barely be seen. I do not currently know the reason behind this problem.
• Tomorrow will be the observing night of DIMSUM, Elana and I are dealing with ssh issues. I am trying to get access to the actual network rather than a guest.
• Currently sources are not perfect Gaussians, some of them are decent. It may be a plane of focus issue.
• If the issues are not fixed, I will only work with clearly seen sources, Get a mock DIMSUM run and hope for the best for a data that would be good for a paper.

12/13/22: Day 6:

• Today was the final day before the observations.
• Make the pegboard more stable by mounting onto ground from additional places.
• Ran the test before, everything was successful.
• The data was noisy, the night should be better.

The night of observing:

• The sources and trials are documented in DIMSUM_observing_analysis.ipynb
• The sources were out of focus and not all sources were identifed.
• Tried to fix it as best I as I could. Seem to be having no doughnuts but sources are worse than the trial.
• I will still try to run the analysis and see if there is anything significant. Source extractor does a pretty good job of identifying bad sources.

Notes from the observations themselves:

Stubbs comments- 

This looks like great progress, bravo. We need to be sure the cables and other elements are not trip hazards, and so I suggest running them under the grating floor somebow. Also the camera isn't pointed quite in the direction I was expecting but I'm sure you guys have that figured out. Finally, we need to be sure we aren't obstructing the new in-dome illumination system that Patrick and Parker are installing. 
Happy to arrange a time to talk over zoom tomorrow if you like.
