David's BCAL Photon Time Resolution Studies

• γ BCAL #sigma;_t vs. dE (GeV):

Time Resolution Segmentation Ratio

• γ BCAL σ_{t_1234} / σ_{t_334} vs. dE (GeV):

• Fits to γ BCAL σ_{t_1234} / σ_{t_334} vs. θ in dE bins:
• Don't trust fits at low-θ, so linearly-interpolate between 12 and 16 degrees.
