FCAL

Thrown photons

PhotonEvsTheta thrown FCAL.png

Reconstructed photons

PhotonEvsTheta recon FCAL.png

Good photons

These are the reconstructed photons whose angles match up with the thrown photons: |\theta _{{recon}}-\theta _{{thrown}}|<0.2^{\circ } && |\phi _{{recon}}-\phi _{{thrown}}|<3.5^{\circ }.

Good photons

These are the reconstructed photons whose angles match up with the thrown photons: |\theta _{{recon}}-\theta _{{thrown}}|<5^{\circ } && |\phi _{{recon}}-\phi _{{thrown}}|<4^{\circ }.
