The system comprises 4 feeds, 8 channels and 4 Broadband Polarimeters. 16 data channels, 2 total
power and 2 polarization signals per feed are recorded. This total power system is being used in a
"software beamswitching" mode to observe extended sources. The feeds are mounted in a row in
azimuth direction, having distances of approximately 3, 9 and 5 arcmin.
The RF-filter is essential to protect against TV-satellites.
The system needs special offline reduction programmes. Non-MPIfR users should contact
E. Fürst or W. Reich for information.
