The data structure JTMED contains the standard tracking parameters ( CUTS and flags to control the physics processes) which are used by default for all tracking media. It is possible to redefine individually with GSTPAR any of these parameters for a given tracking medium. For example to change CUTGAM to 0.0001 for tracking medium ITMED: CALL GSTPAR(ITMED,'CUTGAM',0.0001)
For more information on default values for IDRAY and ILOSS see [BASE040].
The default tracking medium parameters are stored in the bank whose pointer is stored in the JTMED variable. In this case in the above table JTMN = JTMED. In the case one or more of the above parameters has been modified for a specific tracking medium, the whole parameter set is stored in the next bank of the given trackin medium. In this case JTMN = LQ(JTM) in the above table, where JTM is the pointer to the bank of the tracking medium, i.e. JTM = LQ(JTMED-ITMED).
Note
At tracking time the parameters above are copied from JTMN into the common blocks /GCCUTS/ and /GCPHYS/. GSTPAR must be called before GPHYSI.
