Antenna temperature towards blank sky using the L-band receiver at a rest frequency of 1410 MHz (Scan 2). (Postscript Version) The spectral processor was used in the 2x1024 mode with a bandwidth of 40 MHz. Frequency switching was used with an offset frequency of 1 MHz. The red and green lines correspond to the linear X and Y polarizations respectively. The TRACK procedure was used to track blank sky.
