In this work , we provide 2189 photometric- and kinematic-selected member candidates of 24 star clusters from the LAMOST DR2 catalog .
We perform two-step membership identification : selection along the stellar track in the color-magnitude diagram , i.e. , photometric identification , and the selection from the distribution of radial velocities , i.e .
the kinematic identification .
We find that the radial velocity from the LAMOST data are very helpful in the membership identification .
The mean probability of membership is 40 % for the radial velocity selected sample .
With these 24 star clusters , we investigate the performance of the radial velocity and metallicity estimated in the LAMOST pipeline .
We find that the systematic offset in radial velocity and metallicity are 0.85 \pm 1.26 km s ^ { -1 } Â and -0.08 \pm 0.04 dex , with dispersions of 5.47 _ { -0.71 } ^ { +1.16 } km s ^ { -1 } Â and 0.13 _ { -0.02 } ^ { +0.04 } dex , respectively .
Finally , we propose that the photometric member candidates of the clusters covered by the LAMOST footprints should be assigned higher priority so that more member stars can be observed .
