If for some reason a calibration file is not found, the program should STOP execution, otherwise we get dubious results. In the particular case of the BB, this would not neccessarily be easy to see, since (at least in the repository version) the only quantities stored are BB-Z and BBt0. I suppose that these could appear reasonable even with an unreasonable calibration. > > Cheers, > Claus Jorgensen & Djamel Ouerdane About the RedHat versions....what is the current 'default' version at BNL. I have seen mails from Konstantin about RH7.0, but I guess the rcf linux machines run 6.1. We at NBI have 5.2, 6.1 and 6.2, and will wait until at least 7.1 to upgrade. So...maybe 7.0 is a bit premature? Cheers, -- Ian-------------------------------------------------------------------- | I.G.
