Array parameters August 2012 (20/07-14/10)

LABOCA was cooled down mid-July to be ready for the Chilean, ESO, and Swedish time blocks starting shortly thereafter. It was used until being warmed up in mid-October.

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. Channel 93 is variable and can usually be used.
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 don't show astronomical signal and are considered bad.
6, 45, 114, 133, 199, 204, 206, 208, 211, 213, 219, 228, 309	Bad channels, not showing any astronomical signal or very low signal levels, unconnected to groups 4 or 7 above.
18, 65, 77, 257	These channels are variable and usually usable. Check your data.
241	No proper signal. Picks up signal from channels 248 (strong) and 296 (weak).
