Understand

Dark Energy Spectroscopic Instrument (DESI) uses more than 2.4 million Emission Line Galaxies (ELGs) for 3D large-scale structure (LSS) analyses in its Data Release 1 (DR1).

Such large statistics enable thorough research on systematic uncertainties.
In this study, we focus on spectroscopic systematics of ELGs.
The redshift success rate ($f_{\rm goodz}$) is the relative fraction of secure redshifts among all measurements.
