The pigments given in the Luo et al’s work [2] have been revised based on the apparent thermal energy, Ea,B, and the m value.

It is seen that the A1 Bufo rhodopsin and the A1 mouse rhodopsin have similar λmax values (λmax = 500 nm) while their Ea,B were different. This causes a significant difference in the m values. Another m value is obtained for the A1 human red cone, which is again different than the ‘exclusive’ value m = 45. These results indicate that the m = 45 value is not a unique value for the all pigments.
