2 | // Analysis task for 'mini' sub-package | |
3 | // Contains all definitions needed for running an analysis: | |
4 | // -- global event cut | |
5 | // -- a list of track cuts (any number) | |
6 | // -- definitions of output histograms | |
7 | // -- values to be computed. | |
8 | // Each one must be defined using the "CREATE" methods, which | |
9 | // add directly a new element in the task collections, and don't | |
10 | // need an external object to be passed to the task itself. | |
