The files have an XML-like format which will be described below. |

54 | | The first line in the <event> block has a special meaning: In the first column it contains the number of particles (N) and in the third column the weight (w) of the event, while the other columns can contain additional parameters (which are not used in the current GiBUU implementation). For real events, the weight w equals 1 (i.e. all events have the same weighting). For perturbative events, on the other hand, the weight is usually related to the total cross section for the process (and can be different for each event). |
| 56 | The first line in the <event> block has a special meaning. The columns of these first lines have the following meaning: |
