Detailed Description

This class contains double hit correction used in low-flux events.

The double hit correction is given by

\[ h_{r}(\eta) = \frac{\sum_i N_{i,strips hit}(\eta)}{ \sum_i N_{i,total hits}(\eta)} \]

where \( N_{i,strips hit}(\eta)\) is the number of strips in the \(\eta\) bin that had one or more hits in event \(i\), and \(N_{i,total hits}(\eta)\) is the total number hits in the \(\eta\) bin.

These are generated from Monte-Carlo truth information.
