Detailed Description

Task for detailed charge-size analysis of STS hits.

This class inherits from FairTask and CbmStsAnaBase and is designed to perform detailed analysis of charge and size correlations in STS (Silicon Tracking System) hits.

Key functionalities include:

Charge Correlation: Analyzes the correlation of charge between the p-side and n-side of STS sensors.
Time Correlation: Analyzes the correlation of time between the p-side and n-side cluster forming a hit.
Cluster Size Correlation: Evaluates the size correlation between p-side and n-side clusters.
Charge vs. Size Analysis: Performs charge versus cluster size studies separately for each sensor side.
Hit Type Separation: All analyses are performed separately for:
- All hits (all) - includes all reconstructed hits.
- Track hits (trk) - includes only hits associated with reconstructed tracks.
