Summary

Google Doc 20230626UT Night Log

TMS/FPIA test:
  • The program is working as intended. We exercised the cases where FPIA succeeded and failed (through control-C), and the case where TMS failed when taking a reference. We also observed how, in single-sided mode, if we started the TMS loop on a particular side, and ran dofpia, then after dofpia finished successfully, the reference on that side was taken and the loop was resumed. (But TMS always stayed with the same side, regardless of which side FPIA was run on - more work could be done here, although it doesn't seem all that realistic at the moment).
  • Note that when IDL is launched with "lbc_idl", then after dofpia is exited with control-C, in order to send control back to TMS one has to exit the IDL session. This is because IDL does not have a way to trap control-C. So launching FPIA from a terminal window using "idl -e "dofpia_new, …" is more convenient; one doesn't have to restart lbc_idl from the terminal window.
  • We didn't go through the case where FPIA failed because no pupils were found. This one could probably be done closed-dome.
  • We also did not explicitly test dohybrid, though no surprises are expected with it as it has the same exit structure as dofpia. Nevertheless - we can try it another time.
  • Next Actions:
    • Set up the background process that manages the FPIA/TMS switching on the observing workstations (YZ).
    • Implement a shortcut for running the LBC IDL using the command "idl -e " (e.g. idl -e 'dofpia, /x2, /blueonly, /backout') from a terminal window. (YZ, OPK)
    • Work on the single sided mode if warranted (mixing the sides is not a operational use-case at the time) (YZ)
    • The goal is to have this running during restart.

LBC phot standards:
  • 2 Clem & Landolt fields & 1 sdss+Y field were observed.
  • Clear conditions at the start of the night, although during the 2nd half clouds came in.

LUCI2-DIQ:
  • The IQ on the AO reference star at FeII was good, better than earlier this month when this same field was observed.The PSFs of stars are elongated in a radial direction from the AO ref star, which was not seen before. Under investigation.
    • But last night, this star fell into Bin2 as it appeared 0.1 mag fainter to the WFS than before, when it fell into Bin 1.

Tasks

LBC Collimation Test (priority 1)

  • Testing modifications to dofpia that will stop the TMS loop before collimation and take the reference/start the TMS loop after successful convergence. Contingent on daytime testing. I've stated "any" conditions to improve the chances, but within the range where FPIA can converge (poor seeing acceptable, but not thick cloud)

LBC Standard Fields

MODS Standards

  • Imaging Standard (priority 2)
    • M92 Field
    • photometric conditions required
  • MODS Spectrophotmetric Standard (priority 3)
    • BD 33
    • photometric conditions required

LUCI2 AO imaging test (priority 1)

  • Test focus and image quality on sky in potential science filters ( Ks, H, H2, BrG, J)
  • Test offset z if needed
  • Use Juan Carlos PSF morphology field for verification

LBC Thermal testing

This test will collect a series of extra-focal pupil images like FPIA takes (but with a specific OB and using all 4 chips) while driving the mirror temperatures up and down. In past tests, it has taken 6 hours to complete 1/2 sine curve. The pupil images will be analyzed to understand the aberrations that develop as a function of temperature gradients on the primaries. Seeing < 1.4" needed.
