Dear Erik It is nice when you get easy questions. If you call BrRdoModule* bbMod = new BrRdoModule(.. bbMod->SetInpuMode(1); it will not use the cal files but def values in the DetectorParams. One could also ask yury to make a default files (calibration ) for sim data. /fv ------------------------------------------------------ Flemming Videbaek Physics Department Brookhaven National Laboratory tlf: 631-344-4106 fax 631-344-1334 e-mail: videbaek@bnl.gov ----- Original Message ----- From: "Erik Jakobsen" <jakobsen@hehi03.nbi.dk> To: "BRAHMS DEV" <brahms-dev-l@bnl.gov> Sent: Monday, May 14, 2001 7:49 AM Subject: BrRdoModuleBB > > Dear BRATs > > I have a question concerning the BrRdoModuleBB (and more generally the > other detectors).
