surface_rtpropFromTypesAverage

Extracts surface RT properties by averaging.

This method allows to let one pencil beam calculation represent an area when it comes to surface RT properties. The surface is sampled at a set of positions. The sampling is defined as a set of angles by the WSV dlos.

A weight must be specified for each angle by dlos_weight_vector. These weights should represent the solid angle each dlos covers, but can also include other weighting factors such as antenna pattern. The sum of dlos_weight_vector is internally normalised to 1.

All the output variables are a weighted average between the surface types inside the area sampled.
