Notes. Column. 1: IceCube event name; Col. 2: 4FGL or 4FGL-DR2 or identification (in case of new sources) of candidate γ-ray counterpart; Col. 3: name of the source associated with the γ-ray candidate neutrinos counterpart and of the candidate neutrinos counterparts without a γ-ray association; Cols. 4,5: radio coordinates (RA, Dec, inferred from the VLBI observations analysed in this work) of the radio sources associated with the objects indicated in Col. 3. There are two possible radio counterparts associated with WISEA J111439.67+122503.7, which are indicated with A and B. Column 6: Angular separation of the associated radio source from the neutrino (ν) best-fit position and Col. 7: from the γ-ray source best-fit position; Col. 8: classification of the associated source from the Fermi catalogue or from the NED. The latter catalogue is consulted when the γ-ray sources are non-associated in the Fermi catalogue. These sources are marked with (b). Column 9: Spectroscopic redshift of the associated source. WISEAJ065633.43+053922.7 and NVSS J065916+055252 have no γ-ray counterpart reported. (BLL = BL Lac; G = galaxy object; FSRQ = Flat spectrum radio quasar; IrS = infrared source; XrayS = X-ray source; BCU = blazar candidate or unknown in the 4FGL classification; BC = blazar candidate according to the VOU_Blazar tool (the tool is described in Chang et al. 2020), and the BC classification is reported in Giommi et al. (2020b).
