Popis: High-precision measurements of radial velocities of the M67 cluster members are used to calculate the radial-velocity dispersions in the stellar groups found earlier in the cluster’s corona. The previously detected feature in one of the groups (Group 60) consisting of stars with almost identical space velocities was confirmed. The possibility of more accurate future studies of the parameters of star groups using the Gaia catalogues is discussed.
