Arxiv: The GLASS-JWST Early Release Science Program. IV. Data release of 263 spectra from 245 unique sources Published: 8/29/2024 7:23:14 PM Updated: 8/29/2024 7:23:14 PM

Paper abstract: We release fully reduced spectra obtained with NIRSpec onboard JWST as partof the GLASS-JWST Early Release Science Program and a follow-up Director'sDiscretionary Time program 2756. From these 263 spectra of 245 unique sources,acquired with low (R =30-300) and high dispersion (R~2700) gratings, wederive redshifts for 200 unique sources in the redshift range z=0-10. Wedescribe the sample selection and characterize its high completeness as afunction of redshift and apparent magnitude. Comparison with independentestimates based on different methods and instruments shows that the redshiftsare accurate, with 80\% differing less than 0.005. We stack the GLASS-JWSTspectra to produce the first high-resolution (R ~ 2700) JWST spectraltemplate extending in the rest frame wavelength from 2000~\AA\ to 20, 000~\AA.Catalogs, reduced spectra, and template are made publicly available to thecommunity.
