Despite the snowy forecast from earlier in the week, tonight is mostly clear. Seeing at the start is about 2 arcsec FWHM on the guider.
AIP guys are testing various presets and guiding and different beam splitter combinations, so there are not many notes here.
I changed the magnitude zeropoint to 25.3 (normal AIP AGW is 28.0) to improved PFU acquisitions. Note that this is an empirical correction, and not
the 22.8 that Jesper calculated last night (we don't yet understand the difference).
I shortened the RSCALE distance to 15 arcsec to reduce the chances of picking up the ghost in the lower left quadrant.
