Rate-safe Counting for Relative Luminosity

I have begun considering the "rate-safe counting" method for computing the relative luminosities, using techniques from

Deciding on Rt cut - Jet Meeting

During the Jet meeting, Carl pointed out and wanted to see what percentage of events have an Rt of 1. So to make that more clear, I've made and attached the following plots:

Pythia Multiplicity Selection Effect on Jetlike Near-side Yield

Motivation:

It is observed that the near-side jet peak distribution differs from central and peripheral d+Au collisions.

SSd geometry update

The SSD geometry also have quite apperent problems,- many steps through volumes.
I found several volumes that are the final but declared many
