31 // History:
32 // -----------
33 // 31 Jul 2001 MGP Created, with dummy implementation
34 // 12.09.01 V.Ivanchenko Add param and interpolation of parameters
35 // 04.10.01 V.Ivanchenko Add BindingEnergy method
36 // 25.10.01 MGP Many bug fixes, mostly related to the
37 // management of pointers
38 // 29.11.01 V.Ivanchenko New parametrisation + Excitation
39 // 30.05.02 V.Ivanchenko Format and names of the data files were
40 // chenged to "ion-..."
41 // 17.02.04 V.Ivanchenko Increase buffer size
42 // 23.03.09 L.Pandola Updated warning message
43 // 03.12.10 V.Ivanchenko Fixed memory leak in LoadData
