<div dir="ltr">To be honest I don't really have details. It was mentioned for one of the Atlas top analyses which performs a fit "after unfolding". The contact for that analysis is a graduating student who won't have time to implement in Rivet, so it's unclear when we will actually have someone attempting to write this thing. I think it'd be better if we did not provide a fitting library (even via dependency).<div class="gmail_extra"><br><div class="gmail_quote">On Wed, Dec 7, 2016 at 1:55 PM, David Grellscheid <span dir="ltr"><<a href="mailto:david.grellscheid@durham.ac.uk" target="_blank">david.grellscheid@durham.ac.<wbr>uk</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span><br>

</span>I'm still very excited about removing GSL completely, so we'll have to<br>
look at that individual case. Is it such a complicated minimization that<br>
we need something like Minuit for it or can we make use of a simpler<br>
function we can include in the analysis?<br>
<br>
