Incidence angle image COSMO SkyMed

For Sentinel-1, it comes from the incidence angles in the geolocation grid within the product metadata annotation. For Cosmo-Skymed, a grid is created based on the near and far incidence angles in the metadata. The tie point grids created by SNAP are then interpolated on the fly for each pixel in the product.

I don’t know if it’s lost when using Gamma format.
