Skydip calibration
On Nov. 22, the calibration scan was corrupted due to a computer crash at the telescope. To recover calibration data for this day, we've made an absolute calibration on 3 channels from a central array beam map. We extend this calibration to the other channels by calculating a relative calibration using skydip information from that day.
The beam plot of the array. The channels which detected Uranus are shown in green.
Individual Channel Maps. The fitted beam is drawn in white. A the beam produced from a full Uranus beam scan during the same observing run is drawn in black.
