Two questions on HistFactory

Dear experts,

I have two simple questions on the HistFactory tool that I cannot seem to find the answers to online.

1.) I want to quote the best-fit values and fit uncertainties on the fit parameters. HistFactory seems to perform multiple calls to the MINUIT functions such as MIGRAD. I am assuming the correct values (with most reliable uncertainties) are those provided by the final table produced by HistFactory, i.e. the final call to MIGRAD. Is this assumption correct?

2.) Is there a way to produce the post-fit distributions with bin-by-bin fit errors from the fitted model using

Thank you for any help or advice.
