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.
l_insert_hinges(x, y, h)
numeric vector (sorted in increasing order)
a numeric vector giving the wavelengths at which the y values should be inserted by interpolation, no interpolation is indicated by an empty vector (numeric(0))
a list with variables
y. Unless the hinge values
were already present in
y, each inserted hinge, expands the vectors
by two values.
