Fig. 7. SSH (Stavenga et al., 1993) and GFRKD (Govardovskii et al., 2000) vitamin A1 templates fitted to sciaenid spectral ERD data by maximum likelihood. Only estimates from best fitting models from Table 2 were plotted for each species. Values to the right of each pigment label are estimated _max and pigment specific weight as estimated by the model. P1 (blue) is the short wavelength pigment, P2 (yellow) is the long wavelength pigment, and P3 (where applicable; green) is the intermediate pigment. Black lines represent additive curves developed by summing the product of each curve weighted by the estimated weighting factor. White circles are mean photopic spectral sensitivities from Fig. 4. For weakfish, B refers to the estimated peak of the P2 β-band.
