3 am Chile Dec 6. Kicked off repeat 500 ./CommunicateTrial2023.sh, along with python data xfer script. This is with stopped-down aperture.
Thursday plan:
check vertical extension and perhaps move it to avoid telescope obscuration

I was confused by inapprorpriate CR to FITS file conversion. The PSF's aren't saturated. In fact we could use more flux.
This method works well (on Chris' laptop) for file conversion:
mdcraw -o 1 -D -4 -T CU2A0987.CR2
convert CU2A0987.tiff CU2A0987.fits
That makes a nice, well-behaved FITS file. PSF is about 40 microns across, which I think means for a 300mm focal length we are basically getting resolved images of the fiber tips, for a 600 micron fiber.
For next time, perhaps use smaller fiber diameters.
I used gphoto2 to change the lens aperture to f/6.3. I was worried we were getting aberrations at faster f-number but I now think it's just fiber tip illumination non-uniformity.
I also removed the ND filter in the optical path. There is now no filter in the beam. Wasn't able to debug why no light in the vertical panel. Might just leave that for next time. It's vignetted by telescope anyway.
started another data collection into 23-12-06_observing_run directory on La Cie disk.
