This script package, CASPER, is designed to determine reliable stellar parameters (temperature, metallicity, surface gravity, and carbon abundance) of low/medium-resolution stellar spectra for cool Carbon-Enhanced Metal-Poor (CEMP) stars (Teff < 5000K). This package is under development for public use and thus needs more testings and refinements (Whitten, Yoon, et al. in prep). The description of the CASPER methodology can be found in Yoon, Whitten, et al. 2020 (The Astrophysical Journal, 894,7). The detailed documentation, along with the codes, will be available for public use in the near future.
If you want to use this package for your scientific use and/or help to complete the development, please contact first both Devin Whitten (devin.d.whitten@gmail.com) and Jinmi Yoon (jinmi.yoon@gmail.com).
