---|
33 | // ----------- |
---|
34 | // 31 Jul 2001 MGP Created, with dummy implementation |
---|
35 | // 12.09.01 V.Ivanchenko Add param and interpolation of parameters |
---|
36 | // 04.10.01 V.Ivanchenko Add BindingEnergy method |
---|
37 | // 25.10.01 MGP Many bug fixes, mostly related to the |
---|
38 | // management of pointers |
---|
39 | // 29.11.01 V.Ivanchenko New parametrisation + Excitation |
---|
40 | // 30.05.02 V.Ivanchenko Format and names of the data files were |
---|
41 | // chenged to "ion-..." |
---|
42 | // 17.02.04 V.Ivanchenko Increase buffer size |
