make:

$ make READ-NBODY-TAIL
$ make READ-NBODY-RT
$ make READ-NBODY-2RT

Usage example:

For stars inside tidal radius:

$ READ-NBODY-RT OUT3 my_simulation 0 0

Restarted run example:

$ READ-NBODY-RT OUT3 my_simulation 150000 100000.0

For stars inside two*tidal radius:

$ READ-NBODY-2RT OUT3 my_simulation 0 0

Restarted run example:

$ READ-NBODY-2RT OUT3 my_simulation 150000 100000.0

For stars inside tidal radius and tidal tail:

$ READ-NBODY-TAIL OUT3 0 0

Restarted run example:

$ READ-NBODY-TAIL OUT3 150000 100000.0

In this new version, snapshots are saved in the snapshot folder and tidal tail stars are saved in the tail folder. This requires an nbody6 input parameter file with KZ(23)=3.
