% Psychtoolbox:PsychColorimetricData.
%
% Colorimetric data and some data driven colorimetric calculations.
%   i) Subfolder ColorimetricMatFiles contains .mat files with basic data.
%
%   ii) Functions here return various standard data -- many routines
%   take a string argument that allows access to estimates from different
%   sources.
%
% The data routines here are closely coupled to the calculation routines
% in PsychColorimetric.  The conceptual dividing line between the two folders is
% somewhat blurry.
