barak.spec.scale_overlap(w0, f0, e0, w1, f1, e1)[source]¶

Scale two spectra to match where they overlap. Assumes spectrum 0 covers a lower wavelength range than spectrum 1. If no good regions overlap, regions close to the overlap are searched for.

Returns:

scale_factor : float
    Multiply spectrum 1 by scale_factor to match spectrum 0.
