Add apothem and radius of small silicon cells.
Take into account also half cells in silicon wafers by using the same sensitive detector of full cells. Extend number of cells to 132 for both CEE and CEH.
Include auxiliary class to calculate x and y position of small si cells.
Add functions to calculate MIP signal per layer and tag pion interacting layer in CEE according to CMS publication.
Access PDGID and energy of primary particle using the PrimaryGenAction and save info in root format.
Use SignalHelper class methods to tag interacting pions in CEE and save interaction layer in ROOT output file.
Add version control for overlap check method. Define it only for G4-11.0 and up.
In order to find layer of corresponding nuclear interaction in CEE, pass vector of signals already calibrated at the MIP scale. Use an auxiliary lambda function for in EventAction.
Add printout information for SignalHelper IsInteraction() method.
To identify CEE interaction layer check also if the layer has at least 3 Si cells above threshold.
Apply the same stragy to tag interacting pions in CHE as done in CEE. Simply consider the central Si pad for CHE layers. Save corresponding layer number in ROOT file.
Fix bug when accessing signals per CHE layer in EventAction EndOfEvent method.
Add simplified method for Birk correction. To be used only for comparison with the CMS one.
Add units for Brik1 coefficient as done in CMSSW. It restores a-dimensionality of Birks Law. Remove density convertion to g/cm3 for consistency.
Update value of MIP calibration constants for silicon and tiles.
Discard events interacting in the first two layers of CEE, or not interacing both in CEE and CHE or with interacting layer not found. Use CEEInteracted variable to select CEE and CHE events. Perform gaussian fit to extract response as the pick value of distributions (as written in TB paper) by fitting around maximum of histograms.
