Workspace Method sensor_responseMixerBackendPrecalcWeights

Description

Includes pre-calculated response covering mixer and backend.

This method acts similar to sensor_responseBackend, but uses
pre-calculated weights. These weights can also include the effect
of mixer and sideband filtering.

As usual, f_backend gives the frequency of the channels. This WSM
has no direct influence on the result, but at least representative
values must be set.

The frequency response is defined using channel2fgrid_indexes and
channel2fgrid_weights.

Both channel2fgrid_indexes and channel2fgrid_weights are assumed
to be common for all viewing directions.
