Elimination of unreliable data from the analysis.A, Frequency of the SDs of the five individual settings (in log units) averaged to produce each of the data points for protanopes (open bars; 2410 data points) and deuteranopes (filled bars; 3820 data points); 3.4% of the data points, the five settings of which had SDs > 0.15 log unit, were eliminated from the analysis. The SD axis is truncated at 0.5 log unit. A few points had SDs higher than 0.5.B, Frequency of the log residuals between the data points and the first fit of the spectral sensitivity model [see Eqs.1, 2, and 3a for protanopes (open bars; 2290 points) and deuteranopes (filled bars; 3730 points)]; 2.6% of the data points, the residuals of which were >0.20 log unit, were eliminated from the second fit of the model.
