Hi Radek, I have certainly also seen this. My understanding of the code is that in the richmodule for each track a pid- object is created, and this has either R=0 or R>0. In the dst class the algorithm looks for valid pid object attached to a track. So the -1111 mean that no object was found, which In fact is a bit curious. In short I do not think this ought to happen unless there are many tracks in bfs (>3). Maybe someone else has looked more closely at this?

I want to ask you a question about RICH. In the DSTs there are tracks that have rings with some radius. There are also tracks that supposedly don't have ring attached to it - but the problem is that some have ring radius set to 0 and others have it set to -1111. What is the difference between them? new year's greetings radek _______________________________________________ Brahms-dev-l mailing list Brahms-dev-l@lists.bnl.gov http://lists.bnl.gov/mailman/listinfo/brahms-dev-lReceived on Mon Jan 2 15:33:36 2006
