Workspace Method x2artsSensor

Description

Maps x to sensor variables.

Maps OEM's state vector, x, to the matching ARTS variables. This
method handles variables associated with the sensor. If you retrieve
other variables, make sure that you also call x2artsAtmAndSurf
 and/or x2artsSpectroscopy.

The following retrieval quantities are handled by this method:
   Pointing
   Frequency shift and stretch
   Baseline fits

Should only be used inside inversion_iterate_agenda.

Elements in x representing pointing corrections are mapped to
sensor_los. Elements representing frequency corrections are mapped
to f_backend. Baseline variables are mapped to y_baseline.

The sensor response is recalculated if there is any non-zero frequency
correction.
