Dynamical analysis of NGC 110: cluster of fainter stars or data
  fluctuation?
  The stellar enhancement of the cluster NGC 110 is investigated in various
optical and infrared (IR) bands. The radial density profile of the IR region
does not show a stellar enhancement in the central region of the cluster. This
stellar deficiency may be occurring by undetected fainter stars due to the
contamination effect of massive stars. Since, our analysis is not indicating
the stellar enhancement below 16.5 mag of I band, therefore the cluster is
assumed to be a group of fainter stars. The proposed magnitude scatter factor
would be an excellent tool to understand the characteristic of
colour-scattering of stars. The most probable members do not coincide with the
model isochronic fitting in the optical bands due to poor data quality of P P
MXL catalogue. The different values of the mean proper motions are found for
the fainter stars of the cluster and field regions, whereas similar values are
obtained for radial zones of the cluster. The symmetrical distribution of
fainter stars of the core are found around the best solution of isochrone. The
mass function and mass segregation studies are not possible due to higher
uncertainty of the photometric data. The number of the massive stars of the
cluster region is low in comparison with the field region due to completed
evolution life of the massive stars.
