Residuals from the 13-parameter model fits (Equation 7) as a function of predicted threshold. Residuals are defined as log10(measured threshold) − log10 (predicted threshold), where both measured and predicted thresholds are in units of stimulus modulation amplitude (Equation 4). Models were fit independently to data collected at each visual field location. Residuals from each subject are plotted in a different color (see inset).
