With the FHC Zoffset is 948 cm. Pion+, pion- , neutron and anti-neutron are shot to the center of FHC, and the positions on the surface of FHC are (124,5,948), (124,-5,948). The energy of particles are 60 GeV and I digitized

the energy for one count is 50 Mev.

the geometry of the FHC and FMS is

http://www.star.bnl.gov/protected/spin/xuanli/FHC/FHC_948/Energy60_corrected/,

the related folder name is FMS/, FHC/, FMS+FHC/ and FMS_FHC. File name with pi are for pion+, with pim are pion-, with n are neutron, with an are anti-neutron.

For example, pion+ arrives at the position (124, 5, 948) which is on the surface of FHC.
