M Dwarf Machine (MDM)

STELLAR PARAMETRIZATION OF LAMOST M DWARF STARS

Created by [email protected], Fri. Mar. 13 2020.

Getting Started

MDM does not need to install locally, but it requires download models pre-trained by SLAM (https://github.com/hypergravity/astroslam). The trained model of MDM is on the basis of stellar parameters of APOGEE DR16. Users can download trained models on ASPCAP_DR16.dump. For more details, see "Stellar Parameterization of LAMOST M Dwarf Stars"

Version 0.2.0
Add Mgiant module: The trained model of LAMOST M giant stars is on ASPCAP_DR16_mgiant.dump.
