% PURPOSE: Generate output of temporal disaggregation methods
% ------------------------------------------------------------
% SYNTAX: td_print(res,file_sal,op1);
% ------------------------------------------------------------
% OUTPUT: file_sal: an ASCII file with detailed output of
% temporal disaggregation methods (td)
