  We report results on the analysis of eleven new Milky Way open cluster
candidates, recently discovered from the detection of stellar overdensities in
the Vector Point diagram, by employing extreme deconvolution Gaussian mixture
models. We treated these objects as real open clusters and derived their
fundamental properties with their associated intrinsic dispersions by exploring
the parameter space through the minimization of likelihood functions on
generated synthetic colour-magnitude diagrams (CMDs). The intrinsic dispersions
of the resulting ages turned out to be much larger than those usually obtained
for open clusters. Indeed, they resemble those of ages and metallicities of
composite star field populations. We also traced their stellar number density
profiles and mass functions, derived their total masses, Jacobi and tidal
radii, which helped us as criteria while assessing their physical nature as
real open clusters. Because the eleven candidates show a clear gathering of
stars in the proper motion plane and some hint for similar distances, we
concluded that they are possibly sparse groups of stars.
