Workspace Method antenna_responseGaussian
Description
Sets up a Gaussian antenna response.
This method works as antenna_responseGaussianConstant but allows
to inlude a frequency variation of the antenna width. Here the FWHM
is specified at a set of frequencies. These frequencies will also be
the frequency grid of antenna_response.
If *grid_width* is set to <=0, the grid width will be twice the max
value in *fwhm*.

Synopsis
| antenna_responseGaussian( | antenna_response, f_points, fwhm, grid_width, grid_npoints, do_2d ) |
Variables
| OUT | antenna_response | (GriddedField4) | The antenna pattern/response. |
| GIN | f_points | (Vector) | Frequencies at which FWHM is defined. |
| GIN | fwhm | (Vector) | Full width at half-maximum of the Gaussian function. |
| GIN | grid_width | (Numeric, Default: -1.0) | Full width of grid (negative value gives 2*fwhm). |
| GIN | grid_npoints | (Index, Default: 21) | Number of points to represent the grid, see above. |
| GIN | do_2d | (Index, Default: 0) | Set to 1 to create a 2D antenna pattern. |
