  "abstract": "In our previous work in Xiao et al. (2019), we suggested that 6 superluminal sources could be gamma-ray candidates, and in fact 5 of them have been confirmed in the fourth Fermi-LAT source catalogue (4FGL). In this work, based on the 4FGL, we report a sample of 229 Fermi detected superluminal sources (FDSs) including 40 new FDSs and 62 non-Fermi detected superluminal sources (non-FDSs). Thus, we believe that all superluminal sources should have $\\gamma$-ray emissions, and superluminal motion could also be a clue to detect $\\gamma$-ray emission from active galactic nuclei (AGN). We present a new approach of Doppler factor estimate through the study of the $\\gamma$-ray luminosity ($L_{\\rm \\gamma}$) and of the viewing angle ($\\phi$).",
