BDSB 23
(MWSC 3497)
Summary
BDSB 23 is a sparse, very loose object of low C3 quality. It is located at a large distance from the Sun, above the mid-plane. It is poorly studied in the literature.
This object shares a very small percentage of members with a later reported entry.
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.
