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