| - | * Use the sampled points to compute values for variables such as HT(jets), dphi(jets), MT(lepton, MET), etc. | + | * Use the sampled points to compute values for "composite" variables such as HT(jets), dphi(jets), MT(lepton, MET), etc. |
| * Compare feature spaces between analyses, find and visualize overlaps and exclusions. | * Compare feature spaces between analyses, find and visualize overlaps and exclusions. | ||
| + | * As a very simple first step, we simply check if two analyses are disjoint in any of the basic variables. | ||
