%% One thing to try is seeing how the fit changes when you constrain
%% all the e0 parameters for a data set to be the same.  DO NOT edit
%% the path include files to change the e0 math expressions.  Instead,
%% do something like this:
%%    guess	e0o_ti		0.0
%%    set	e0eu_ti		e0o_ti
%%    set	e0ti_ti		e0o_ti
%% In general it is a good idea to write your input files with lots of
%% flexibility in terms of the parameters.  By switching guesses and
%% sets in this manner, you can quickly and easily try all sort of
%% different fitting models and constraints between parameters.
%%
%% See the Commentary for a discussion of how the value for amp_ti was
%% determined.  It is a good trick, when the data supports it.
