Detector Geometry Versioning

• STAR Geometry Versioning:

  • the steering file:  $STAR/pams/geometry/geometry/geometry.g
  • contains the complete history of the STAR configurations
  • calls the constructors of individual detector subsystems and sets some of their parameters
  • versioning is done at run time based on the value of “geometry” parameter.
  • Example: detp geometry year2003

• The detp command allows the user to set certain predefined configuration parameters:

  • Configurations : year_1a,s,b,h,c;year_2a,
  • year2000, year2001, year2002, year2003
  • Gcalor : Gcalor_on, Gcalor_off
  • Geant Physics : Hadr_on, Hadr_off (GHEISHA)
  • Geant Physics : Phys_off, Decay_Only
  • Geometry Detail : mwc_off, pse_off, 4th_off
  • Magnetic Field : Field_on/off, field=value
  • Auxillary keys : Debug_on/off
