Notes. (1) Redshift. (2) Galaxy ID. (3) Class: SF = star forming, GV = green valley, Q = quiescent. (4)-(6) Time when the galaxy formed 10%, 50%, and 90% of its stellar mass, as derived from TNG50. (7)-(9) Time when the galaxy formed 10%, 50%, and 90% of its stellar mass assigned during radiative transfer calculations. (10)-(12) Time when the galaxy formed 10%, 50%, and 90% of its stellar mass, as derived with pPXF from noiseless spectra.
