Candidate Vetting ================= :doc:`GWCelery ` orchestrates and supervises performing basic data quality and detector state checks, grouping of events from individual pipelines into :doc:`superevents `, initiating automated :doc:`sky localization and parameter estimation `, inferring :doc:`classification and source properties `, and sending alerts. A Data Quality Report is prepared that consists of a semi-automated detector characterization and data quality investigation for each event. It provides a variety of metrics based on auxiliary instrumental and environmental sensors that are used by a rapid response team in order to make a decision of whether to confirm or retract a candidate. The rapid response team consists of commissioning, computing, and calibration experts from each of the detector sites, pipeline experts, detector characterization experts, and follow-up advocates.
