Overview of the data sets II and III together: (a) Histogram of the number of series (“#Series”) having a certain number of points (“#DataPoints”); the insets indicate the fractions of non-available numbers (“#Nans”) and the fraction of unclassified points (“#Unclass.”) from the total number of points (“TotPoints”). Here TotPoints = #DataPoints + #Nans, while #DataPoints = #SaccadePoints + #FixationsPoints + #UnclassifiedPoints, where #FixationsPoints and #SaccadesPoints are the number of points classified as fixations and saccades respectively. The figure also shows the histogram of the number of points from the total number of data points belonging to (b) fixations and (c) saccades, in one single series. The insets in (b) and (c) indicate the corresponding histogram of the size (number of points) of each single fixation and saccade, respectively. One individual fixation (resp. saccade) is defined as a set of consecutive points all labelled as “fixation” (resp. “saccade”). We call the total amount of fixations and saccades as “TotFixations” and “TotSaccades” respectively. Here “TotSeries” = 502, “TotPoints” = 4.8 × 106, “FixationPoints” = 2.5 × 106 and “SaccadePoints” = 9.2 × 105. See also Table 1.
