## Line vs continuum system temperature

Figure shows the system temperature as a function of the radio frequency. The can vary significantly over the large bandwitdh of the 2SB NOEMA receivers. Figure shows the minimum and maximum system temperature inside the IF bandwidth for all possible local oscillator tunings. As a result, for continuum estimation, a frequency averaged is interpolated from a pre-computed table. The relevant frequency in that case is the LO frequency of the tuning (see Fig. ). The averaging is done such as
