hcrs_to_hgs

sunpy.coordinates.transformations.hcrs_to_hgs(hcrscoord, hgsframe)[source]

Convert from HCRS to Heliographic Stonyhurst (HGS).

Even though we calculate the parameters for the affine transform, we use FunctionTransformWithFiniteDifference because otherwise there is no way to account for the induced angular velocity when transforming a coordinate with velocity information.
