 \section sim_s3  Tracking of particle in the magnetic field
 
-GEANT has two ways for tracking charged particles in the 
+GEANT has two integration methods for tracking charged particles in the 
 magnetic field: HELIX et RKUTA.
 HELIX is faster and works well if the gradient of magnetic 
 field is small.

 spectrometer. The choice of HELIX or RKUTA is done in the
 config file when the magnetic field is defined:
 <pre>
-  AliMagFMaps* field = new AliMagFMaps("Maps","Maps", TRACKING, FACTOR, MAXB, AliMagFMaps::k5kG);

-TRACKING must be 1 for RKUTA and 2 for HELIX (the default value for aliroot is 2 (HELIX))
-FACTOR allows you to set the magnetic field to 0, just putting FACTOR=0. Default value is 1.
-MAXB is the maximum magnetic field which is 10.T
+INTEG must be 1 for RKUTA and 2 for HELIX (the default value for aliroot is 2 (HELIX)).
+FACTOR_SOL, FACTOR_DIP allow you to set the multiplicative factor for solenoid
