Notes. The complete table is available at the CDS. Columns: (1) ID LEGA-C of the file associated with the spectrum. (2) Mass-weighted age estimated from fits, using Equation (1); we assume a fixed error of 0.07 dex for all galaxies (see Appendix B). (3) Mass-weighted metallicity estimated from fits, using Equation (2); we assume a fixed error of 0.06 dex for all galaxies (see Appendix B). (4) Average formation time estimated using Equation (3). (5) Δτ ≡ τ95 − τ5, where τx is the time at which a galaxy formed x percent of its mass, as measured from its SFH (see Section 5.1).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
