The ModelFest Baseline Dataset consists of four thresholds from each of 16 observers for each of 43 stimuli. These data are contained in the file modelfestbaselinedata.csv. This ascii file has the format "comma separated value" and can be easily opened in Microsoft Excel, Matlab, Mathematica, Word, and many other applications. Internally it consists of 16 lines, one for each observer, and each line starts with the observers initials, followed by the four thresholds for stimulus 1, then the four thresholds for stimulus 2, and so on. Each threshold is expressed in units of log10 contrast, with three decimal places of precision.
A more extensive description of these data, along with extra measurements and conditions, are contained in html pages, or as a single down-loadable Excel spreadsheet.
