- Fix the emergency fixes.
- Add all the possible sources to the pegboard. The more the merrier.
- Find out an ND filter combination that accounts for the divided light that have different brightness. The different brightness should not matter because we expect the shape to be the same as long as they are visible and not saturated.
- Make sure we get a distribution of sources that makes the DIM value with respect to distance saturate so that we can correlate with fwhm of the observations when the time comes.
- At this point it should be ready for further tests and data collection
- Test whether the light from the sources affect the telescope dome.
- If not:
- Tie the optical fibers to the rail to address the trip hazard.
- Run the cables under the grating.
- If it is, try not to make it affect:
- Either increase the value of the ND filters.
- Put SM1 tubes to the sources and wiling to be sacrifice the number of sources.
- If nothing works, do the server connection Tiago asked.
- If not:
- Once the test of dome interference is done, make a night test taking actual data and try to correlate the saturated differential image motion data with the fwhm.
- Do not forget to enjoy the stars and the experience the Magellanic Clouds.
Day 4: 12/09/22:
- The sources from the day before with ghosting effects before the camera and flashes get out of phase, for some reason camera did not take pictures of the flashes:
I only was able to take a screenshot of the 4 sources but they give the essential idea. These images should not be considered other than observing that sources were initially not good. The left panels is the initial trial and right one is after a focus change. These trials made us realize that we need to fix the camera movement issue. - We tried to figure out why the photos were out of sync with the sources. We could not figure it out why it had worked before and stopped working. Then we just decided to average out any latency by just making the exposure 1/200 seconds rather than 1/2000.
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.
