Column Descriptions

Basic galaxy properties derived for the CLASSY sample.
See Berg+2022 for a full overview of these properties, along with a detailed description of computation methods and references.

 

Target - CLASSY sample name, where objects are designated by an abbreviation of their sexigesimal coordinates as JHHMM±DDMM. *Some targets are linked to their respective optical SDSS spectra.

Alt Name - Alternative names for target from literature.

RA - Right ascension in sexigesimal format at the J2000 epoch.

Dec - Declination in sexigesimal format at the J2000 epoch.

z - Redshift from optical emission lines.

Zneb - Nebular oxygen abundance derived using the Te "direct" method, relative to solar metallicity (where Z☉ is defined as 12+log(O/H) = 8.69, Asplund+2021).

log M★ - Total galaxy stellar mass in units of M☉ derived from optical + IR SED fitting.

log SFR - Total galaxy star formation rate (M☉ yr-1) derived from optical + IR SED fitting.

log sSFR - Total galaxy specific star formation rate (yr-1), computed as log(SFR/M★).

ne - Nebular electron density (cm-3) derived from the [S II] λ6717 / λ6731 ratio.

O32 - The [O III] λ5007 / [O II] λ3727 ratio as a proxy for ionization field strength.

E(B-V) - The reddening derived using the Balmer decrement and the Cardelli et al. (1989) extinction law.
