Photopic luminosity function
p = luminos(lambda) is the photopic luminosity function for the wavelengths in lambda [m]. If lambda is a vector (Nx1), then p (Nx1) is a vector whose elements are the luminosity at the corresponding elements of lambda.
Luminosity has units of lumens which are the intensity with which wavelengths are perceived by the light-adapted human eye.
