[Rivet] Jet rates in JADE_OPAL

[Frank Siegert]

Hi Riveters,

I noticed that the JADE_OPAL analysis crashes at

  jet.clusterSeq()->exclusive_ymerge_max(2);

(for Durham and Jade finders). It works fine, if I use

  jet.clusterSeq()->exclusive_ymerge(2);

but from the FastJet documentation it sounds like ymerge_max would be the 
really correct thing to use (even though in practice I guess it doesn't 
make a difference).

Hendrik, since you are an expert with these two jet finders, have you 
noticed this somewhere else? I saw that in your analyses you are using 
ymerge instead of ymerge_max for some reason.
With the fastjet-jade.patch it used to work fine, by the way.

Any ideas, or should I forward this to the fastjet guys?

Cheers,
Frank
