double  minmass,
double  maxmass,
double  dRmax,
bool  clusterPhotons,
bool  trackPhotons,
double  masstarget = 91.2*GeV 
)

Constructor taking single eta/pT bounds and type of the leptons, mass window, and maximum dR of photons around leptons to take into account for Z reconstruction. It has to be specified separately whether such photons are supposed to be clustered to the lepton objects and whether they should be excluded from the remaining FS.

const PROJ& addProjection ( const PROJ &  proj,
const std::string &  name 
) [inline, protected, inherited]

Register a contained projection. The type of the argument is used to instantiate a new projection internally: this new object is applied to events rather than the argument object. Hence you are advised to only use locally-scoped Projection objects in your Projection and Analysis constructors, and to avoid polymorphism (e.g. handling ConcreteProjection via a pointer or reference to type Projection) since this will screw up the internal type management.

(Yes, some experiments make a difference between clusterPhotons and trackPhotons!)
