Notes. Columns 3–5 are the values of the parameters in Col. 1 from different works (see text). RV and Vt are the radials and tangential velocities of the cluster respectively. [Fe/H], Dist, and logt are the isochrone fitting results for metallicity, photometric distance, and age of DC 3, respectively. In this work, RV and Vt are calculated by the average radial and tangential velocity of the cluster members with Pm > 0.5. The number of members included in the calculation of these two parameters is listed in column 6.
