Workspace Method f_gridFromSensorHIRS
Automatically calculate f_grid to match the sensor.
This method is handy if you are simulating a HIRS-type instrument,
consisting of a few discrete channels.
It calculates f_grid to match the instrument, as given by the nominal
band frequencies f_backend and the spectral channel response
functions given by backend_channel_response.
You have to specify the desired spacing in the keyword *spacing*, which
has a default value of 5e8 Hz.
The produced grid will not have exactly the requested spacing, but
will not be coarser than requested. The algorithm starts with the band
edges, then adds additional points until the spacing is at least as
fine as requested.
There is a similar method for AMSU-type instruments, see
