fit_flux

What does "fit_flux" do?  

Suppose I load a grating spectrum C(h) grating ARF A(E), and RMF
R(h,E), where in this context h represents the grating wavelength.
If I flux_corr the spectrum I will get some quantity denoted by F(h).
Then does fit_flux assume that F(h) related to the model s(E) by

   F(h) = \int dE R(h,E) s(E) ,

independent of the kernel?

I "googled" this but did not find the answer except for this comment:

    % Now do the fit...  ('fit_counts' folds the model
    % through the instrument response; 'fit_flux'
    % would fit the model directly to flux-corrected
    % data if such is available -- the latter is sometimes
    % appropriate for high-resolution data.)

Finally, I noticed that the mailinglist archives are not publically
available.  Are there any plans to make them accessable?

Thanks,
--John
