List of small, almost trivial, problems with the Monte Carlo

1. Density of polystyrene is 1.032 g/cm^3.  PDB quotes 1.06.

    ===> bicron has density of 1.032 g/cm^3... so that's where it comes from.

2. Radiation length in Pb is 0.56000 cm.  PDB quotes 0.56123 cm.

3. A of Pb is 207.19.  PDB quotes 207.2(1).

4. Polystyrene differs from PDB values:

                 MC       PDB
=====================
density      1.03     1.06     g/cm^3
rad len       42.0    43.8     g/cm^2

             (or 43.26?)
had len      75.0     81.7     g/cm^2
% C            92.3     92.3
% H            7.7       7.7  

5. Question -- the energy deposits in the pre- and postshower layers... are they handled properly?  i.e., at some point, perhaps in the slow simulator, the energy needs to be divided between PRE/POST readout and the tower readout.

6, Hmmm...
