On the radial velocity calibrations in the LAMOST Medium-Resolution Spectroscopic Survey of Nebulae

Juan-Juan Ren, Hong Wu, Chao-Jian Wu +12

Accurate radial velocity determinations of optical emission lines (i.e. [NII]$\lambda \lambda$6548,6584, H$\alpha$, and [SII]$\lambda \lambda$6717,6731) are very important for investigating the kinematics and dy…
