Definitions:

The CDDC's and CTC's are meant to set up the pointing so that pixel 5 is centered on the ASC, or actual source coordinate. If you want some other pixel to be centered on the ASC, then you have to add the pixel pointing offset for that pixel. The pixel pointing offsets are tabulated below, assuming a 3.3 arcmin pixel separation and a 24 degree rotation of the array on the sky. These figures for the array footprint were derived by analyzing the 11 x 11 map of rcw57(West) taken on April 12, 2003 at 20 hours 15 minutes UT.

Note that the pixel pointing offsets are in real degrees, not degrees of azimuth. CDCC's are by convention stated in degrees of azimuth.
