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.
|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.|
# Handle inverted channels (all): data.Data *= array(-1,'f') # Variable channels (check your data und uncomment): #bad = [ 22, 23, 24, 32 ] #flagC(bad)
