6 | // Class for handling of ESD track cuts |
7 | // |
8 | // TODO: |
9 | // - add functionality to save and load cuts |
10 | // - fix the n sigma cut so it is really a n sigma cut |
11 | // - add different ways to make track to vertex cut |
12 | // - add histograms for kinematic cut variables? |
13 | // - upper and lower cuts for all (non-boolean) cuts |
14 | // - update print method |
15 | // - is there a smarter way to manage the cuts? |
