*This example shows how one can obtain the cluster size |
3 |
*distribution for tracks generated by the Heed program. |
4 |
*Since Heed does not generate clusters but always delta |
5 |
*electrons (they usually have a very short range), we use |
6 |
*the NODELTA-ELECTRONS option on the TRACK command. This compresses |
7 |
*the delta electrons into clusters. |
