λ_max and rhodopsin absorption nomogram curve data for each wild type and modified visual pigment examined in the study

NA = not available (see “Results”). Correlation coefficient = coefficient of the fit of the nomogram curve to the absorption or sensitivity data. R = rhodopsin, M = metarhodopsin, SS = spectral sensitivity data.
