Detailed Description

MonteCarlo vertex.

Simulated vertex - source of MC tracks (contains GEANTs VTX bank information and much more)

int PaMCvertex::iBeam ( ) const [inline]

index of beam particle in PaEvent::vecMCtrk. ...

Valid only for primary vertex. For all other vertices returns -1

Referenced by Print().

bool PaMCvertex::IsPileup ( ) const [inline]

"true" for pseudo vertex, emitting pileup track.

"Pileup vertex" is the vertex with only 1 track, without mother track, and with Z far upstream ( < -800 cm)

bool PaMCvertex::IsPrimary ( ) const [inline]

"true" for primary vertex.

By COMGEANT convention, "primary" vertex is the first in the list of MC vertices.
Primary vertex also do not have "mother" track.

int PaMCvertex::iTrackOfOrigin ( ) const [inline]

index of mother particle (incomming trajectory) in PaEvent::vecMCtrk. ...

Warning:: Primary vertex and "pileup" vertices do not have mother particle (i.e.function returns -1).

Referenced by Print().

int PaMCvertex::NMCtrack ( ) const [inline]

Number of outgoing MC tracks in the vertex.

Warning:: In the primary vertex beam track is also counted as "outgoing" (see FAQ for more details)
