 v14 $N_\textrm{exc} = N_\textrm{sig} - N_\textrm{bg}$ where \{N_\textrm{sig}\) is the number of events identified as potential gammas from the source direction ('on-source') and $$N_\textrm{bg}$$ the number of gamma-like events measured 'off-source'. Note that for Simulations, $$N_\textrm{bg}$$ is not necessarily zero for wobble-mode observations as an event can survive the analysis for on- and off-events, if this is not protected by the analysis chain. where $$N_\textrm{sig}$$ is the number of events identified as potential gammas from the source direction ('on-source') and $$N_\textrm{bg}$$ the number of gamma-like events measured 'off-source'.
