Offset | Variable name | Data type | Meaning |
1 | Px | REAL | best estimate for x-component of momentum [GeV] |
2 | Py | REAL | best estimate for y-component of momentum [GeV] |
3 | Pz | REAL | best estimate for z-component of momentum [GeV] |
4 | E | REAL | best estimate for energy [GeV] |
5 | m | REAL | mass of particle [GeV] |
6 | Q | REAL | charge of particle |
7 | Imp(R,phi) | REAL | transverse impact parameter, in units of sigma |
8 | Imp(R,z) | REAL | longitudinal impact parameter, in units of sigma |
9 | NTRK | INTEGER | number of charged particles contributing |
to the energy flow object | |||
10 | type | INTEGER | particle code according to PYTHIA convention, |
999 = cluster of unresolvable particles |
In cases of NTRK > 1, the largest impact parameters are recorded.
This record is repeated NEFLOW times.
