VizieR Online Data Catalog: Observed sample of z~0.7 massive galaxies (Gallazzi+, 2014)

The sample has been selected from the COMBO-17 catalog of the Extended Chandra Deep Field South (E-CDFS) survey (Wolf et al. 2004A&A...421..913W, Cat. II/253; see also Section 2.4.1) to have photometric redshift (or spectroscopic when available) in the range 0.65=<z=<0.75 and to have stellar mass larger than 1010 M_ȯ (as estimated from spectral energy distribution (SED) fitting by Borch et al. 2006A&A...453..869B). These criteria give a sample of 717 galaxies (of which 200 already had a spectroscopic redshift from the literature at the time at which the targets were selected). We further restrict the selection to galaxies with apparent R-band magnitude R<22.7, which allows sampling the red sequence down to its completeness limit of 3x1010 M_ȯ at this redshift (Borch et al. 2006A&A...453..869B) and the massive end of the blue cloud. From the so-selected sample of 521 galaxies we observed a final sample of 77 galaxies with a single IMACS mask designed.
