Q Band OOF results from Jan 8, 2008

Q Band results (Todd)

Because these scans were taken in AzEl? mode rather than Encoder mode, I had to compute azoff and eloff in post-processing. This included calculating precession from J2000 to the current epoch, annual aberration, and applying the refraction correction from the Antenna file. The diurnal aberration term was ignored as it is <= 0.3 arcsec. The resulting scan pattern is very nearly centered at 0,0. The buildoof2008.py script will perform these corrections whenever it encounters data recorded in AzEl? mode. The fits on this page include up to 5th order Zernikes, to be consistent with the corresponding Mustang plots.
