Determine the globular-cluster nature of Minni 19

Determine whether the Galactic-bulge candidate Minni 19 is a genuine globular cluster whose radial-velocity distribution overlaps that of the Galactic disk or bulge, or whether no cluster exists at that location.

Background

The analysis modeled the observed radial-velocity distribution of Minni 19 as a combination of Galactic disk and bulge populations. The disk-and-bulge model fit the observations adequately, so the authors could not identify a separate radial-velocity component attributable to a cluster.

The authors explicitly caution that this result does not establish the absence of Minni 19: a genuine cluster could be hidden because its velocity distribution overlaps the field-star distributions. Thus, the physical nature of Minni 19 remains unresolved.
