Workspace Method doit_scat_fieldCalcLimb

Description

Calculates the scattering integral field in the DOIT module (limb).

The scattering integral field is the field generated by integrating
the product of phase matrix and the Stokes vector over all incident
angles.

For limb simulations it makes sense to use different
zenith angle grids for the scattering integral part and the RT part,
because the latter part requires a much finer resolution near
90 degrees. Taking an optimized grid for the RT part and an equidistant
grid for the scattering integral part saves very much CPU time.
This method uses the equidistant za_grid defined in
DOAngularGridsSet and it should always be used for limb
simulations.
