Superevent section

• "possibly from different pipelines" --> :doc:`different pipelines </procedures/searches>
• "A multi-interferometer trigger is always preferred over a single-interferometer trigger irrespective of the type of search." --> Here, I think it is confusing since we are not going to single IFO triggers. Or maybe, clarify the point that single IFO alert will be send if it is in coïncidence with a EM counterpart or neutrino.

"statistic for Burst" --> :doc:`Burst </procedures/searches>

"statistic for CBC" --> :doc:`CBC </procedures/searches>

• "In case of an offline trigger upload from a pipeline, no preliminary GCN will be sent." --> I don't think it is relevant to be mentioned here already in the Alert Timeline
• Can you add to this part the OPA alert threshold: 90% of purity for CBC and 1/yr for Burst (TBConfirmed)
