From: Forty-four years of studying light adaptation using the probed-sinewave paradigm Journal of Vision. 2006;6(10):3. doi:10.1167/6.10.3 Figure Legend: Plots of the four summary measures (different panels) for the high-contrast flickering-background results shown in Figure 4 (and the “B” data set from Figure 9). All four summary measures are plotted as a function of the flickering background's temporal frequency. Left panels plot dc level (relative probe thresholds averaged across phase). Right panels plot peak-to-trough distance (difference between the peak and the trough of the relative probe-threshold curves). The top panels show the log forms of these summary measures; the bottom panels show the linear forms. The symbols used for the data points are those identifying the columns in Table 1.
