[12/2/15, 2:19:54 AM] Christine Chen: Random question: Is there a reference file with PSF FWHM as a function of wavelength?
[12/2/15, 2:22:49 AM] Maxwell Millar-Blanchaer: not that I know of, but to first order i think it should be lambda/D
[12/2/15, 2:23:00 AM] Maxwell Millar-Blanchaer: with D as 7.7701 meters
[12/2/15, 2:23:14 AM] Maxwell Millar-Blanchaer: (i got THAT value from pipeline_constants.txt)
[12/2/15, 2:26:26 AM] Marshall Perrin: To second order, it's modified by the apodizer and secondary obscuration, and by time-variable AO performance. But conveniently the sat spots are copies of the PSF.
[12/2/15, 2:36:34 AM] Christine Chen: People who work on extended sources might appreciate the sat spot FWHM as a possible header keyword (since it gets tabulated anyways).
