  * 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.
