Notes. Stars with a detected radio source in this work are highlighted. The positions, parallax, and proper motion were obtained from the Gaia DR3 catalog (Gaia Collaboration 2021, 2023), with some exceptions. (a)Hereafter TYC 3301. (b)Star in Gaia DR3 without parallax and proper motions. Position is from Gaia DR3, and parallax and proper motions are taken from the Hipparcos catalog (van Leeuwen 2007). (c)Star in Gaia DR3 catalog without parallax and proper motions. Position is from Gaia DR3, proper motions are from Tycho-2 catalog (Høg et al. 2000) and distance information from Carpenter et al. (2009). (d)Star in Gaia DR3 catalog without parallax and proper motions. Position is from Gaia DR3, proper motions are from the Tycho-2 catalog, and distance information is from da Silva et al. (2009). The last column lists the angular separation between the target source and the phase calibrator.
