Array parameters April 2018
(April 03 - April 19)
Main parameter file: laboca-2018-04.rcp
A new RCP file laboca-2018-04-rcp has been created for the first cool down period of LABOCA 2018,
this is the result of the combination of two beam Maps on Mars (scans 11062 and 11445),
both observed in good weather.
The total number of working backends is 198.
Individual scans
| 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 and are considered bad.
|
| 114, 116,
117, 118, 119, 120, 126, 128, 129, 130, 131, 132, 133, 134, 141, 147,
148, 152, 153, 154, 155, 156 |
Channels located in group 5 / cable L. These channels don't show
astronomical signal (factor 20 below normal) and are considered 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 don't show
astronomical signal and/or cross-talk and are considered bad.
|
| 6, 45, 170, 199, 204,
206, 208, 211, 213, 219, 222, 228, 241, 257, 309 |
Bad channels, not showing any astronomical signal or very low signal levels,
unconnected to groups 4, 5, or 7 above. |
