Calorimetry
- extrapolate final state particles to Cal front face (linear or helix)
- supply <X0>, <L> for each Cal to pick shower start point
- has its own geometry spec for barrel and endcap cals.

- Small:
- EM: s(E)/E = 0.12/?E ? 0.01
- HAD: s(E)/E = 0.50/?E ? 0.02
- Large:
- EM: s(E)/E = 0.15/?E ? 0.01
- HAD: s(E)/E = 0.40/?E ? 0.02
- Both have s(x)=1 and 5 cm for EM and HAD.
