Abstract:
191 individual measurements of radial velocities made with
CORAVEL-type spectrometer are presented for 60 stars in the large
region of NGC 6811 open cluster. Photoelectric UBVR magnitudes are
given for 117 stars - members of the cluster by proper motions.
Spectral classification of these stars is taken from Straizys and
Kazlauskas (1993BaltA...2....1S 1993BaltA...2....1S).
