29 // History:
30 // -----------
31 // 30 Mar 2010 L. Pandola 1st implementation.
32 // 25 May 2011 L. Pandola Renamed (make v2008 as default Penelope)
33 // 09 Mar 2012 L. Pandola Moved the management and calculation of
34 // cross sections to a separate class
35 // 07 Oct 2013 L. Pandola Migration to MT
36 // 23 Jun 2015 L. Pandola Added private member to store the PIXE flag
