Beam study using Saturn observation

Warning:
Saturn is extended (about 20 arcsec) so we expect the main beam to be very large.
Saturn is so bright that it saturates at the center.

Using a decorrelation of the noise

The contours shown correspond to 1/10, 1/100, 1/1000 and 1/10000 of the maximum of the map (which is not well calibrated)

The yellow dots are data points that are negative but for this log plot, we show their absolute value
