Notes. “Distance” and “Scale” are from the Local Group. “Morphology”: Hubble classification. “i” is the inclination angle defined as the angle between the line of sight and the polar axis of the galaxy. It is determined from the axis ratio of the isophote in the B band using a correction for intrinsic thickness based on the morphological type. “PAjet” is measured from radio images at different spatial scales. Specifically, with images generated from NVSS (arcminute scale) and VLBA (arcsecond scale) data obtained at frequencies of 1.4 and 4.8 GHz, respectively.
