Fitting more parameters will improve the rms for any data set but a large number of data points must be obtained to obtain significant results. After moving the antennas only the azimuth offset, APC1 should change. The remaining pointing constants have been determined from independent measurements of mechanical and encoder misalignment and confirmed with more than 12 hours of data. These terms should be consistent from configuration to configuration. The data files below contain all the pointing data for the b1, b2 and b3 configurations.

The TV camera on 3 needs focussing, and the cover spring needs replacing. The CCD chip was burned out because the spring is stretched and will not return the cover. After replacing the CCD chip the camera is now out of focus. The power to the cover motor is now disconnected with the cover closed. The tables summarizes the pointing for optical and radio data.
