Detailed Description

Project out primary particles according to definition.

Mimic an experimental primary-particle definition by projecting out according to particle ID. The projection can be further specialized to accommodate specific experimental definitions.

before()

bool Rivet::Projection::before ( const Projection &  p ) const

Parameters

p	Projection to compare to.

Returns

Equivalent if the projection p is of the same type as this, the cuts are equal, and the list of PDG IDs is the same.
