30 // History:
31 // -----------
32 // 1 Aug 2001 MGP Created
33 //
34 // 09.10.01 V.Ivanchenko Add case z=0
35 //
36 // 9 Mar 2008 MGP Cleaned up unreadable code modified by former developer
37 // (Further clean-up needed)
38 //
39 // 15 Jul 2009 Nicolas A. Karakatsanis
40 //
41 // - LoadNonLogData method was created to load only the non-logarithmic data from G4EMLOW
42 // dataset. It is essentially performing the data loading operations as in the past.
43 //
44 // - LoadData method was revised in order to calculate the logarithmic values of the data
45 // It retrieves the data values from the G4EMLOW data files but, then, calculates the
46 // respective log values and loads them to seperate data structures.
47 //
48 // - SetLogEnergiesData method was cretaed to set logarithmic values to G4 data vectors.
49 // The EM data sets, initialized this way, contain both non-log and log values.
50 // These initialized data sets can enhance the computing performance of data interpolation
51 // operations
