  We present the second data release of the Large Early Galaxy Astrophysics
Census (LEGA-C), an ESO 130-night public spectroscopic survey conducted with
VIMOS on the Very Large Telescope. We release 1988 spectra with typical
continuum S / N ~= 20 /Angstrom of galaxies at 0.6 ~< z ~< 1.0, each observed
for ~20 hours and fully reduced with a custom-built pipeline. We also release a
catalog with spectroscopic redshifts, emission line fluxes, Lick/IDS indices,
and observed stellar and gas velocity dispersions that are spatially integrated
quantities including both rotational motions and genuine dispersion. To
illustrate the new parameter space in the intermediate redshift regime probed
by LEGA-C we explore relationships between dynamical and stellar population
properties. The star-forming galaxies typically have observed stellar velocity
dispersions of ~150 km/s and strong Hdelta absorption (Hd_A ~ 5 Angstrom),
while passive galaxies have higher observed stellar velocity dispersions ~200
km/s and weak Hdelta absortion (Hd_A ~ 0 Angstrom). Strong [O III]5007 / Hbeta
ratios tend to occur mostly for galaxies with weak Hd_A or galaxies with higher
observed velocity dispersion. Beyond these broad trends, we find a large
diversity of possible combinations of rest-frame colors, absorption line
strengths and emission line detections, illustrating the utility of
spectroscopic measurements to more accurately understand galaxy evolution. By
making the spectra and value-added catalogs publicly available we encourage the
community to take advantage of this very substantial investment in telescope
time provided by ESO.
