This allows to compute combined CLs and combined cross-section upper limits.

These SSRs were implemented in the PAD and thus have recently been updated with their covariance information. The {{{info}}} file is attached to this page as concrete example with a reduced number of signal regions. 113 114 The subset description will be printed to the output file with the results from simplified likelihood combination, after the usual exclusion information: 113 115 {{{ 114 116 <set> <tag> <cov_subset> <exp> <obs> <CLs> ||
