A Two-level Radial-velocity Zero-point Calibration for LAMOST MRS with Gaia and APOGEE and a Value-added RV Catalogue
A two-level zero-point calibration for LAMOST MRS radial velocities, anchored to Gaia and APOGEE, cuts high-S/N scatter against APOGEE from about 1.1 to 0.5 km/s and ships an 11-million-spectrum catalogue.
