Individual observer data for the 1955 Stiles–Burch 2° pilot investigation

Although the results of the 2 degrees Stiles-Burch investigation were published in 1955 in the form of mean data, individual results have not been available. It is only recently that they have been in wide demand. Since in 1955 this demand was not anticipated, individual results were left in an unprocessed form; the processing has now been completed. Tables are given for each of 10 observers and their mean for color-matching functions, unit (WDW) coordinates, and relative luminous efficiency functions.
