C | Offline External source field loading routine. |
| 13 |
C | This routine is called every time we want to |
| 14 |
C | load a a set of external fields. The routine decides |
| 15 |
C | which fields to load and then reads them in. |
| 16 |
C | This routine needs to be customised for particular |
| 17 |
C | experiments. |
