Notes. Vsys, D, and Scale is the systemic velocity, distance, and scale, respectively, from the Local Group. Morphology is the Hubble classification. i is the inclination angle defined as the inclination between line of sight and polar axis of the galaxy determined from the axis ratio of the isophote in the B band using a correction for intrinsic thickness based on the morphological type. PAphot is the position angle of the major axis of the isophote 25 mag arcsec−2 in the B band measured north-eastwards (see Paturel et al. 1997 and references therein). Reff is the effective radius from Spitzer data. The black hole mass (MBH) is derived from a Keplerian disc model assuming an inclination of 33°(81°) and a distance of 18.11 Mpc. PAjet is the position angle of the jet from VLBI data (covering only the central region of NGC 1052). As the PA depends on the different components of the jet, varying from 60° to 80°, in this work we consider the average value of 70°. See Kadler et al. (2004a) and references therein for further details. SFR is the upper limit to the star formation rate from FIR luminosity (2 × 1042 erg s−1) as measured by Falocco et al. (2020).
