Overview
French 4 is a poorly populated, very loose object of very low C3 quality. Its parallax locates it at a moderate distance, well above the mid-plane. No fundamental parameter values are available for this object. It is rarely studied in the literature, with no articles listed in the last 7 years.
â ī¸ Warning: the low UTI value and no obvious signs of duplication (Cdup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
No fundamental parameters
