Table 2. A summary of fitting parameters for the analysis of ERG b-wave onset time as a function of flash intensity.

ymax [ms] n k [cd·s/m2] y0 [ms]
RGS9 +/+ 119±13 0.22±0.02 0.0013±0.0011 1.4±1.1
RGS9 −/− 127±3 0.23±0.01 0.0017±0.0004 3.4±0.6
R9AP +/+ 123±5 0.25±0.01 0.0016±0.0005 3.4±0.8
R9AP −/− 115±4 0.27±0.01 0.0095±0.0021 2.8±1.0

The data were fitted using Equation 2 (see Materials and Methods); ymax is the asymptotic maximal onset value, n is the Hill coefficient, and k and y0 are fitting parameters (mean ± SEM).
