This directory contains spectroscopic data published in Guo et al.(2021). The spectra are saved as IDL-readable files, as wavelength (in microns) and flux. The flux unit is erg/s/A/cm^2 for Xshooter spectra and is the relative flux for FIRE spectra. To extract the spectra in IDL, please use the following command, with the appropriate file name. IDL> restore,'FILENAME.sav' To extract the spectra in Python, please use the following command: >>> spec_data=readsav('FILENAME.sav') >>> wave=spec_data['wave'] >>> flux=spec_data['flux']
