Receiver temperature

Figure: Fit of the receiver temperature added by the presence of the dual band dichroic on the optical path. The blue/red curves show the data for a LSB and USB LO tuning, respectively. The two curves per frequency and color show the measured results for the two polarizations.

The receiver temperature has two main contributions.
