Hi Djam and Claus, the acceptance map I generated long time ago for Au+Au 90B1000 is also fine as Djam showed. I think I did exactly the same. In the kumac file the field is set as set_field m0 6.31567 and TOFW is set as set_param tofw mode 2 >From the mrs.geo file, the geometry is set as DETECTOR=TPM1 TYPE:TRAK Det size x = 37.4400 cm Det size y = 20.0000 cm Det size z = 36.6000 cm rotation ang = 90.000 deg. Det center x = 94.600 cm Det center y = 1.800 cm Det center z = 0.000 cm DETECTOR=TPM2 TYPE:TRAK Det size x = 67.6800 cm Det size y = 19.8000 cm Det size z = 50.0000 cm rotation ang = 89.660 deg.

Bad slats in TOFW are not considered. slat < 31 and slat > 112 and a few bad slat between 31 to 112. This are from the condition if(fTofCalibration->ValidCalibration(slatNo)) ... Thank you both for kind help. Best regards, Zhongbao ---------- On Wed, 17 Dec 2003, Claus O. E. Jorgensen wrote: > > Hi Zhongbao, > > It could be the field that somehow is set to the wrong value.
