Overview
FSR 1607 is a poorly populated, very loose object of low C3 quality. Its parallax locates it at a moderate* distance, well below the mid-plane, affected by low extinction. It is catalogued as an old cluster (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~2.31 kpc) differs significantly from the median photometric distance (~1.56 kpc).

💡 Note: The parameters are sometimes transformed from their original values to match the format of the columns shown here, see FAQ. The columns DAv, Bfr, BSS correspond to differential extinction, binary fraction, and blue stragglers, respectively. BSS values can be listed as fractions or integers.
