Workspace Method AntennaConstantGaussian1D

Description

Sets up a 1D gaussian antenna response and a matching
mblock_za_grid.

As antenna_responseGaussian, but alsp creates mblock_za_grid.
For returned antenna response, see antenna_responseGaussian.

The length of mblock_za_grid is determined by *n_za_grid*.
The end points of the grid are set to be the same as for the
antenna response. The spacing of the grid follows the magnitude of
the response; the spacing is smaller where the response is high.
More precisely, the grid points are determined by dividing
the cumulative sum of the response in equal steps. This makes sense
if the representation error of the radiance (as a function of
zenith angle) increases linearly with the grid spacing.

The WSV antenna_los is set to 0.
