Notes. Column (1) gives the CAZ J2000 name of the spatiotemporally associated blazar; (2) IceCube ID of the spatiotemporally associated neutrino; (3) arrival MJD of the neutrino; (4) signalness of the neutrino; (5) area of the enlarged ≳90% error region of the neutrino; (6) top-hat weight of the neutrino; (7) presence of the blazar in the RFC† sample; (8) presence of the blazar in the 4LAC sample; (9) temporal association via a BB95 period; (10) temporal association via a prominent BBHOP flare; (11) blazar type from the CAZ catalog; (12) synchrotron peak frequency in log(Hz); (13) redshift; (14) radio variability Doppler factor; and (15) median flux density in the X-ray band (in erg cm−2 s−1). In columns (7)–(10), “Y” means “present”. In columns (9) and (10), “*” indicates an association based on the BB95 as the peak of BBHOP metric (i.e., when the spatially associated neutrino falls within ±2 d of the peak of a prominent BBHOP such that the peak itself is a BB95; see Sect. 2.2.6). For brevity, this table only shows blazar-neutrino spatiotemporal associations with WT > 0.316 (i.e., those with higher than median weight), hiding 96 low-weight associations. The full list of the spatial and spatiotemporal associations is given as an electronic table.
