l_insert_hinges

numeric array (sorted in increasing order)

a numeric array giving the wavelengths at which the y values
should be inserted by interpolation, no interpolation is indicated by an
empty array (numeric(0))

Inserting wavelengths values immediately before and after a discontinuity in
the SWF, greatly reduces the errors caused by interpolating the weighted
irradiance during integration of the effective spectral irradiance. This is
specially true when data have a large wavelength step size.
