Main physical properties of Patchick 125 stars: Panel a: spatial distribution of APOGEE-2S stars (empty circles). The position of Patchick 125 stars is shown with a navy cross, while the two cluster members analysed in this work are highlighted with red unfilled squares. A navy empty circle with a 5′ radius and centred on Patchick 125 is shown for visual aid. Panel b: the Gaia eDR3 proper motion distribution of our sample. Panel c: highlights the metallicity ([Fe/H]) versus radial velocity of APOGEE-2S stars with ASPCAP/DR16 determinations towards the Patchick 125 field (black circles) together with our BACCHUS-[Fe/H] determinations (red symbols). The blue box limited by ±0.05 dex and ±10 km s⁻¹ and centred at [Fe/H] = −1.7 and radial velocity = 95.9 km s⁻¹ encloses our potential cluster members. Panel d: reveals the 2MASS+Gaia eDR3 colour magnitude diagram corrected for differential reddening for Patchick stars within 3′.
