Workspace Method WMRFSelectChannels


Select some channels for WMRF calculation.

The HIRS fast setup consists of a precalculated frequency grid
covering all HIRS channels, and associated weights for each channel,
stored in a weight matrix. (A sensor_response matrix.)

If not all channels are requested for
simulation, then this method can be used to remove the unwanted
channels. It changes a number of variables in consistent fashion:

- Unwanted channels are removed from f_backend. 
- Unwanted channels are removed from wmrf_weights.
- Unnecessary frequencies are removed from f_grid.
- Unnecessary frequencies are removed from wmrf_weights.
