Top left: CAMD for the GCNS systems colour-coded by the magnitude differences of the binary components. Top right: separation vs. G mag difference for the resolved stellar systems in GCNS (orange points). Known members of the Hyades (black triangles) and Coma Ber (blue squares) clusters are highlighted. Bottom left: histogram (solid orange) of separations for wide binaries in the GCNS sample compared to the DR2-based catalogue (dashed black) from El-Badry & Rix (2018). The dotted red histogram corresponds to the separation distribution of GCNS wide-binary candidates adopting the exact boundaries in El-Badry & Rix (2018). Bottom right: physical projected separation distribution for the wide-binary candidates identified in this work (solid orange) compared to those from El-Badry & Rix (2018) (dashed black) and Hartman & Lépine (2020) (dotted blue), restricted to systems within 100 pc.
