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
Maps of Saturn at 1.25mm and 2.05mm
- 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)
Beam profiles at 1.25mm and 2.05mm
- The yellow dots are data points that are negative but for this log plot, we show their absolute value
Far side lobe at 1.25mm and 2.05mm
- The cross correpond to the arms of the secondary miror of the telescope.
Using a logarithmic scale
