Summary

PTB 7 is a poorly populated, very loose object of low C3 quality. It is located at a moderate distance from the Sun, above the mid-plane. It is rarely studied in the literature, with no articles listed in the last 13 years.

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.
