Maps of CasA Obtained with 4 scans in AzEl @nkotf 10 10 angle 0 30 60 azel angle=0,45,90,135 20151031s6 to s9 One scan is 210 seconds. (14min in total)

After an offline analysis with a 3 iteration decorrelation with KIDs outside the source we get the following results: The maps on the left are brightness maps at 2 mm (top) and 1 mm (bottom). The maps on the right are the standard deviations maps at 2 mm (top) and 1 mm (bottom).
