Notes. The first four columns report the information about the neutrino hotspots: the name, the equatorial coordinates (J2000) and the L value. The following three columns report the following information for the candidate 5BZCat blazar counterpart: the redshift, the blazar Fermi-LAT counterpart in the 4LAC-DR3 catalog, and the optical spectrum used in this work (see also Appendices B and E). We collected the redshifts by consulting the most recent literature, and cross-checking the literature value with our analysis of the optical spectrum, when available. Sources proposed as candidate neutrino emitters in other works are highlighted with a ⋄ symbol.aRedshift from Healey et al. (2007). bLower limit on the redshift from Shaw et al. (2013), upper limit from Lainez et al. (2024). cRedshift from Drinkwater et al. (1997). dRedshift from Truebenbach & Darling (2017). eEstimated in this work. fRedshift from SDSS-DR17. gRedshift from Shaw et al. (2013). hTentative estimation z = 1.012 in Dwelly et al. (2017), based on a featureless SDSS−DR13 spectrum. iRedshift from Hewett & Wild (2010). lRedshift from Piranomonte et al. (2007). AFrom this work.
