A constrained linear model for continuum normalization of stellar spectra
Andrew R. Casey, Adam Wheeler, Megan Bedell +3
Inferring stellar parameters and chemical abundances by forward modeling stellar spectra usually requires a spectral synthesis code, or an emulator constructed from a curated train…
