 ¹ These scans are not considered for the averaged parameter file because of their low S/N. Especially Neptune is too weak for beammaps when observed in the unstable afternoon atmosphere.

Notes on individual channels

The 37 channels of SABOCA are working fine most of the time, but see the exceptions below.

Channel #Description
22 This channel is sometimes variable or even bad. Verify the gain on your calibrators and the usability on your target data.
23 This channel shows excess noise in one beammap only (#21449).
