Properties of Radial Velocities measurement based on LAMOST-II Medium-Resolution Spectroscopic Observations
R. Wang, A. -L. Luo, J. -J. Chen +28
The radial velocity (RV) is a basic physical quantity which can be determined through Doppler shift of the spectrum of a star. The precision of RV measurement depends on the resolu…

The Comparison of Stellar Atomspheric Parameters between LAMOST and APOGEE databases
Y. Q. Chen, G. Zhao, C. Liu +8
We have compared the stellar parameters, temperature, gravity and metallicity, between the LAMOST-DR2 and SDSS-DR12/APOGEE database for stars in common. It is found that the LAMOST…
