Please remove from your PID algorithms the MVD one, since the parameters are biased and not updated. This could decrease the PID performance.

Is this still a present problem?

Yes, since nobody is working on it.

Maybe this warning could also be noted in the Rho Tutorial ( http://panda-wiki.gsi.de/cgi-bin/view/Computing/PandaRootRhoTutorial?CGI SESSID=cf3584ad45b0a826f96101f4da3a7d63). In section 2.3. Combinatorics that PID algorithm is exemplarily used for muon PID as follows

Quote:

In our example, we start with muons and anti-muons, selected with loose criterion

RhoCandList muplus, muminus, jpsi;
...
// ... in event loop ...
theAnalysis->FillList(muplus, "MuonLoosePlus","PidAlgoMvd");
theAnalysis->FillList(muminus, "MuonLooseMinus","PidAlgoMvd");

Hi Martin,

thanks for pointing out! I changed the example to PidAlgoStt and mention, that this is just to be understood exemplaritly.

Best,
Klaus
