Detailed Description

This class contains the secondary correction.

The secondary correction is given by

\[ c_{r,v}(\eta,\varphi) = \frac{\sum_i N_{ch,i,v,\mbox{primary}}(\eta,\varphi)}{ \sum_i N_{ch,i,r,v,\mbox{FMD}}(\eta,\varphi)} \]

where \(N_{ch,i,v,\mbox{primary}}(\eta,\varphi)\) is the is the number of primary charged particles that fall within the \((\eta,\varphi)\) bin in event \(i\) with vertex \(v\), and is the total (primary and secondary) charged particles that hit ring \(r\) within \((\eta,\varphi)\) bin in event \(i\) with vertex \(v\).

These are generated from Monte-Carlo truth information.
