@lgray (and @vandreev11), is this part of the changes you were talking about in the upgrade reco meeting this morning?

[vandreev11]

@mark-grimes, @lgray, @pfs
yes, this should be included in the coming release/relvals production.

@mark-grimes just to clarify here, we are waiting first on a zero pileup reprocessing at the lpc to check that everything is ok. We will post plots here with the outcome.

This PR should bring improved event content, increasing the charged hadron fraction and reducing the photon fraction.
