Preferred Label : spectral (photon) effectiveness;
IUPAC definition : The reciprocal of the photon fluence rate, E p 0, at wavelength λ, causing identical
photoresponse, Δ y, per unit time (Δ y Δ t). The effectiveness spectrum is directly
proportional to the conversion spectrum of the sensory pigment, if spectral attenuance
is negligible.;
