The mean radial velocity of the open cluster NGC 6939.
MILONE A.A.E.
Abstract (from CDS):
The systematic motion of NGC 6939 is redetermined in light of the signifiant discrepancies among the published values. Based on the monitoring of 26 evolved stars during two consecutive seasons and an average of almost 12 spectra per star, we find the cluster's mean radial velocity to be -18.98 km s^-1 with an error of ± 0.19 km s^-1.
