/*! @brief The rigidity vs threshold rigidity histogram filling.
 *
 * This class builds a 2D histogram binned in event rigidity modulus (Y axis)
 * and threshold rigidity (X axis). Each 2D bin will contain the number of events whose
 * event rigidity modulus and threshold rigidity (eg., Stoermer cutoff rigidity times a
 * threshold coefficient) lie in that bin. Note that the meaning of this threshold coefficient
 * is the same as in TrkRigGeoCut, so it must have the same value used for TrkRigGeoCut
 * (consider using TrkRigGeoCut::GetThresholdCoeff() to retrieve its value).
 * Events whose threshold rigidity is below the lower limit of the bins are recorded in a vector
 * of event rigidities with threshold rigidity in the "inferior threshold bin", which ranges
 * from zero to the the lowest threshold rigidity of the "normal" bins.
 * It is also possible to recover spillover events. These are defined as events with opposite sign
 * and absolute rigidity greater than a certain value (specified as a constructors' parameter).
 * They will be added to the rigidity overflow bins (YOverflow).
 * Another functionality of this action is the correction of deflection for residual misalignment when
 * selecting data with a fixed MDR cut (which reduces the effective tracker geometry and thus brings up
 * some residual misalignment).
 * For output file naming conventions, see #Finalize.
 *
 * CUT DEPENDENCIES: TrkPhSinCut for single physical track, TrkRigGeoCut for galactic event.
