LEGA-C parameters for 877 galaxies

Dynamical models for 673 galaxies at z=0.6-1.0 with spatially resolved (long-slit) stellar kinematic data from LEGA-C are used to calibrate virial mass estimates defined as M_vir_=K{sigma}'_*,int_^2^R, with Ka scaling factor, {sigma}'_*,int_ the spatially integrated stellar velocity second moment from the LEGA-C survey, and R the effective radius measured from a Sersic profile fit to Hubble Space Telescope imaging. The sample is representative for M*>3x10^10^M{sun} and includes all types of galaxies, irrespective of morphology and color.

We demonstrate that using R=Rsma (the semimajor axis length of the ellipse that encloses 50% of the light) in combination with an inclination correction on {sigma}'_*,int_ produces an unbiased Mvir. We confirm the importance of projection effects on {sigma}'_*,int_ by showing the existence of a similar residual trend between virial mass estimates and inclination for the nearby early-type galaxies in the ATLAS3D survey.
