Notes. RA/Dec – right ascension/declination of the γ-ray localization; Δr – distance to respective radio source position; a (95%) – major axis of 95% localization error ellipse; b (95%) – minor axis of 95% localization error ellipse; Φ – rotation angle of the error ellipse East of North (degrees); Γ – spectral index of power-law fit, (pl) are the values obtained from the pointlike fit and (gt) are values from the gtlike fit; Flux – 20-month average flux (0.1 − 100 GeV) determined from the power-law spectral fit in units of 10-7 ph cm-2 s-1; Pivot Energy – in MeV, this is the energy for which there is no correlation between the flux or normalization and spectral index uncertainties; TS – likelihood test statistic value.
