Class Description

                                                                      
 ATLFast PhotonMaker class.

ATLFPhotonMaker()

ATLFPhotonMaker(const char *name, const char *title) :ATLFMaker(name,title)

~ATLFPhotonMaker()

dummy
printf("ATLFPhotonMaker destructor calledn");

void AddPhoton(Int_t code, Int_t mcparticle, Int_t mother, Float_t eta, Float_t phi, Float_t pt)

            Add a new photon to the list of photons

void Clear(Option_t *option)

    Reset Photon Maker

void Init()

  Create histograms

void Finish()

 Function called by ATLFast::Finish at the end of the job

Int_t Make()

.............................................
  This function searches for isolated photons, by scanning through
  the list of MC particles. If a photon is found, its energy is
  smeared using function RESPHO  and its polar angle using RESTHE.
  Different energy-smearing for low and high luminosity can be invoked.
  Isolated photons are stored in The TClonesArray of photons
  and the energy clusters associated with them are removed.
  Non-isolated photons are not considered further.
.............................................

Float_t PhotonResolution(Int_t keylum, Float_t ene, Float_t pt, Float_t eta)

     parametrizes photon  resolution for low and high luminosity
     parametrization from L. Poggioli and F. Gianotti
         keylum=1   -- low  luminosity
         keylum=2   -- high luminosity

Float_t SmearTheta(Float_t ene, Float_t eta, Float_t theta)

     parametrizes smearing in photon position  theta
     parametrization from F. Gianotti
