Extracts a sun spectrum measured at the given location adds it to suns.

The method allows to obtain the sun spectrum by interpolation from a field of such data. The sun spectrum is expected to be stored as spectral irradiance. It is coverted to the spectral irradiance at the sun’s position.

Unit:

Dimensions: [f_grid, stokes_dim]

This method performs an interpolation onto the f_grid. The point of f_grid that are outside the data frequency grid are initialized according to planck’s law of the temperature variable. Hence, a temperature of 0 means 0s the edges of the f_grid.
