phoebe_compute_passband_intensity ()

int                 phoebe_compute_passband_intensity   (double *intensity,
                                                         PHOEBE_hist *SED,

This function computes passband intensity of the passed spectral energy distribution function and the passed passband transmission function. Passband intensity is defined as:

I = \pi \int SED (lambda) PTF (lambda) dlambda / \int PTF (lambda) dlambda
