Update of membership and mean proper motion of open clusters from UCAC5
  catalog
  We present mean proper motions and membership probabilities of individual
stars for optically visible open clusters, which have been determined using
data from the UCAC5 catalog. This follows our previous studies with the UCAC2
and UCAC4 catalogs, but now using improved proper motions in the GAIA reference
frame. In the present study results were obtained for a sample of 1108 open
clusters. For five clusters, this is the first determination of mean proper
motion, and for the whole sample, we present results with a much larger number
of identified astrometric member stars than on previous studies. It is the last
update of our Open cluster Catalog based on proper motion data only. Future
updates will count on astrometric, photometric and spectroscopic GAIA data as
input for analyses.
