cds-question@unistra.frgalaxiesspectroscopyphotometryChemical abundance indicators are studied using composite spectra, which we provide in tabular form. Tables of line strengths measured from these spectra and parameters derived from these line strengths are also provided. All the objects we analyze were selected from the SDSS database. We selected all objects targeted as galaxies and having Petrosian apparent magnitude 14.5<=r_Pet_<=17.75. To extract a sample of early-type galaxies, we then chose the subset with the spectroscopic parameter eclass<0, which classifies the spectral type based on a principal component analysis, and the photometric parameter fracDev_r_>0.8, which is a seeing-corrected indicator of morphology.2006AJ....131.1288Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/1288CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/131/1288https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/131/1288http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/131/1288https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/131/1288https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/131/1288http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/131/1288GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/131/1288/specComposite spectra, Lick indices, line strengths and abundancesrecnoRecord number assigned by the VizieR team.
