% Radiometric and photometric calculations. See also the closely related
% Psychtoolbox:PsychColorimetric and its related data folders. Sometimes
% it is not entirely clear whether a routine is better classified as
% radiometric or colorimetric. Apologies if our intuitions don't match
% yours.

% Obsolete
% The routines below use specific unit conventions. I now think it is better not to mix unit conversions
% in so intimately with radiometric conversions. These routines have been reimplemented to call
% the newer more unit free versions, but since they are used throughout various user programs are
% kept here for now. Someday we may decide to make them go away.
