Hi,
It is now implemented and available in SVN, Jost has generated the maps for different beam energies, namely:
15.0 GeV/C
11.91 GeV/C
8.90 GeV/C
4.06 GeV/C
1.5 GeV/C
the corresponding maps are:
The dipole itself:
DipoleMap1.1500.root
DipoleMap1.1191.root
DipoleMap1.0890.root
DipoleMap1.0406.root
DipoleMap1.0150.root
in front of the dipole:
DipoleMap2.1500.root
DipoleMap2.1191.root
DipoleMap2.0890.root
DipoleMap2.0406.root
DipoleMap2.0150.root
and the region between dipole and Solenoid:
TransMap.1500.root
TransMap.1191.root
TransMap.0890.root
TransMap.0406.root
TransMap.0150.root
The beam energy can be set in sim macro with:
FairRunSim::SetBeamEnergy(Double_t Energy /** GeV/c */ )
according to the energy the field is selected, for now the selection is as following:
BeamEnergy < 2.0 Map 0150
BeamEnergy < 5.0 Map 0406
BeamEnergy < 10.0 Map 0890;
BeamEnergy < 12.0 Map 1190
otherwise Map 1500;
An example for using this can be found in macro/run/run_sim.C and macro/emc/sim_emc.C
setting this in a simulation session, the RuntimDB will take care that the reconstruction get the proper fields!
regards
Mohammad
