SOLVE RF

Command `SOLVE RF` will solve for the spectral variation of the gain. As for the temporal variations, one can either solve for the baseline gain , or the antenna gains, , with according to the mode selected with `SET RF ANTENNA BASELINE`.

To get sufficient signal to noise in each channel, specific observations of a bright source are normally carried out in each project. There are basically two modes for solving RF bandpass. One can either fit a Chebishev polynomial to the data (low signal to noise ratio) or use the data (or a smoothed version of the data) as the RF solution. In the latter case, the actual solution is linearly interpolated between data points. The mode used is controlled by the command `SET RF FREQUENCY SPECTRUM.`

RF bandpass calibration is done baseband per baseband (see section 2.1). It is hence necessary to select a proper baseband with `SET BBAND` command before solving for the RF. The solution is computed in an intermediate frequency space adapted to each generation of signal transport, selected with `SET X I_F`.
