Preliminary maps do not show any cluster. After scans that are obviously experiencing strong vibrations in the telescope are cut. These are calibrated using skydips and beam parameters referenced to channel 102 with no time constant information. Estimated single map calibration error is 10%.
Only ~60% of possibly good data are used for the following maps.
On source integration time is ~ 75% max integration time
To do:
1. Find the reference channel corresponding to each individual map.
2. Check scan indexing and vibrations on a scan by scan basis.
3. Cuts based on uchead temp? (known correlation between uchead temp and telescope vibrations).
4. Make preliminary December map
