<p>Folks,</p>
<p>Matt tagged a new version of AmpTools, version 0.12.0. See the
release notes <a moz-do-not-send="true" href="https://github.com/mashephe/AmpTools/releases/tag/v0.12.0">here</a>
and below.</p>
<p>I released a new version set that has this new version on board,
<a moz-do-not-send="true" href="https://halldweb.jlab.org/halld_versions/version_4.41.0.xml">version
set 4.41.0</a>. This will become the default at JLab at midnight
tonight.</p>
<p>I am told there are some changes coming down the pike to move
functionality out of halld_sim and rely on AmpTools for those
features.<br>
</p>

<p>This version has a new feature that allows one to successively
randomize<br>
the starting parameters and refit data. Such changes required
modifications<br>
to the general approach for MPI-based fits, and existing MPI
applications are<br>
not likely to work without some modification. See the
DalitzExeMPI/fitAmplitudes<br>
example for how to properly terminate MPI fitting jobs.</p>
<p>When making projections of the fit results in the PlotGenerator
the code now<br>
normalizes fit-weighted MC by a factor determined from the fit
parameters rather<br>
than the integral of the histogram. This allows for plotting
weighted histograms,<br>
e.g., moments of the data, where the weighted bin contents may
have varying<br>
signs.</p>
