Density of Gaia sources in the TAMC. The densities are color coded in stars per 6 arcmin2 (see lateral bar). The shadow produced by the TAMC filaments over the stellar background is readily identified. The two over-dense regions are: the open cluster NGC 1747 located at 550 pc and the asterism or apparent concentration of stars (Cantat-Gaudin & Anders 2020) named NGC 1746. The locations of the GdC2015 candidates with Gaia counterparts within 1200 pc are marked with circles and asterisks, and are color coded by distance. Asterisks represent sources with high-quality Gaia measurements (RUWE ≤ 1.4) and circles denote sources with RUWE larger than this threshold.
