HSC 540
Summary
HSC 540 is a sparse, very loose object of low C3 quality. It is located at a moderate distance from the Sun, below the mid-plane. It was recently reported in the literature.
Warning: contains less than 25 stars with P>0.5 estimated.
Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicates that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
