The data are a large set of threshold measurements for detection of Gabor pattern targets presented in the presence of Gabor pattern pedestals. Both targets and pedestals were modulated along a number of different lines in color space. The methods are described fully in [1], along with a summary of the results and some discussion. The complete threshold data set is tabulated here (text file, file contains description of data format). The page will look a little ugly when you view it from your browser, but if you save it as text and read it in with a spreadsheet (such as Excel, use tab delimited), it should fall nicely into place.
