State Default

This is the default state of PTC. All parameters are set to false. For example, in the default state, time is not used and a cavity is present, i.e., Time=false and Nocavity=false. Thus for example.

 STATE=DEFAULT0
 CALL TRACK(R, X, I1, I2, STATE)

tracks a particle X(1:6) replacing cavities by drifts and using path length and momentum rather than the more correct time and energy.
