33 // 1 Aug 2001 MGP Created
34 //
35 // 09.10.01 V.Ivanchenko Add case z=0
36 //
37 // 9 Mar 2008 MGP Cleaned up unreadable code modified by former developer
38 // (Further clean-up needed)

41 //
42 // - LoadNonLogData method was created to load only the non-logarithmic data from G4EMLOW
43 // dataset. It is essentially performing the data loading operations as in the past.
44 //
45 // - LoadData method was revised in order to calculate the logarithmic values of the data
46 // It retrieves the data values from the G4EMLOW data files but, then, calculates the
47 // respective log values and loads them to seperate data structures.
48 //
49 // - SetLogEnergiesData method was cretaed to set logarithmic values to G4 data vectors.
50 // The EM data sets, initialized this way, contain both non-log and log values.
51 // These initialized data sets can enhance the computing performance of data interpolation
52 // operations
