| + | * There are three plugins: | ||
| + | * CMS_2015_I1372730_Z: Z only plots | ||
| + | * CMS_2015_I1372730_G: gamma only plots | ||
| + | * CMS_2015_I1372730: all plots including ratios | ||
| + | * the plugin with the ratio plots can only be run on a sample with both Z and gamma events with correct relative cross-section | ||
| + | * otherwise to get the ratio plots one should run the first two plugins and then make the ratio (will try to provide a script, but just send the plots to vitaliano.ciulli@cern.ch and I will do it) | ||
