20100720 Pointing residual plot

20100720. First plot of the differences between the azimuths and
elevations derived from astrometric fits to StarCam data and those
based on the telescope location (tracker at 0, structure told to go to
various azimuths). These data should help us characterize any
polar misalignment of the pier. The data were taken
in steps of 30 degrees, with 10 degree offsets between three different
sets, all in a counterclockwise direction. (plot courtesy of Tim!)
