Time-of-Flight Geometry Utilities.
A package of geometry routines for the STAR Time-of-Flight detector. Methods include initialization from STAR dbase or local table (xdf-file) and extrapolation routines of tracks to the TOF slats.
Also mappings for DAQ-id to Slat-Id and vice-versa are available as through member functions.
To do:

| StThreeVectorD StTofGeometry::tofPlaneNormPoint | ( | const Int_t | slatId | ) | const |
calculate the normal vector to a slats-plane
tofSlatNormPoint and tofPlaneNormPoint do not always match each other because of uncertainties in phi measurments. but the difference is small.
