Human cone spectral sensitivities or cone fundamentals. The Stockman & Sharpe (2000) functions are provided either as ascii csv (comma separated values) files, as ascii xml (extensible markup language) files, as html tables, which appear in your browser window, or as dynamic graphical plots. Select the data format, the data stepsize and the data units and click the "Submit" button. The other functions are provided in quantal or energy units as ascii csv files, returned as files with the *.csv extension. Click on the buttons for the data files or on "Plot E" or "Plot Q" for energy or quantal plot, respectively. For further details and references click .
