Discovery of Four New Clusters in the Cygnus Cloud
  We report the discovery of four new open clusters (named as QC 1, QC 2, QC3
and QC 4) in the direction of Cygnus Cloud and select their members based on
five astrometric parameters (l, b, \varpi, \mu^*_{\alpha}, \mu_{\delta}) of
Gaia DR2. We also derive their astrophysical parameters for each new cluster.
Structure parameters are generated by fitting the radial density distribution
with King's profile. Using solar metallicity, we performed isochrone-fitting on
their purified color-magnitude diagrams (CMDs) to achieve the age of the
clusters. The known cluster NGC 7062 at adjacent area is chosen to verify our
identification process. The estimated distance, reddening and age of NGC 7062
are in good agreement with the literature.
