Array parameters March 2009 (09/03-31/03)
SABOCA was cold between 9th of March and 31st of March. Before that period, the wafer of SABOCA that was in use during 2008 was replaced by a different one, which basically means a completely new bolometer array. The channels parameters are therefore completely different, and all 37 channels are working.
Besides that, all channels now have the same sign; they are all inverted (for hardware reasons).

Notes on individual channels
All channels of SABOCA are usually working fine except those mentioned below. Furthermore, all backend signals are negative.
Channel # | Description |
---|---|
22, 23 | These channels show variable gain. Check on calibrators. |
24 | This channel had a very low gain in scan 7550. |
32 | This channel was bad in scan 9889, but fine in the others. Check your data. |
