Array parameters October 2010 (15/09-20/11)

LABOCA was not used during the first half of September (but always kept cold). After that period, the channel offsets were found to have changed, thus a new set of array parameters has been created.
LABOCA was in continuous use until it has been warmed up on the 20th of November.

Notes on individual channels

Note: Channels which are terminated with a resistor are not listed in the following table anymore.

Channel #	Description
101, 103, 106, 110	Strong cross-talk: 101↔106 and 103↔110. 101 and 103 may be usable for point sources only.
81, 82, 83, 84, 85, 86, 89, 90, 91, 92, 93, 94, 96, 136, 159, 160	Channels located in group 4 / cable M. These channels usually don't show any astronomical signal. Although they are variable to some extent, we consider them as bad.
177, 179, 180, 182, 183, 184, 185, 191, 192, 201, 202, 203, 205, 207, 217, 218, 220	Channels located in group 7 / cable A. These channels mostly don't show astronomical signal and are considered bad.
6, 114, 204, 208, 213, 228, 257, 309	Bad channels, not showing any astronomical signal or very low signal levels, unconnected to groups 4 or 7 above. Channel 257 is variable and may be usable.
241	No proper signal. Picks up signal from channels 248 (strong) and 296 (weak).
