Luminous early-type field galaxies at $z\sim 0.4$ - I. Observations and redshift catalogue of 581 galaxies

J. P. Willis, P. C. Hewett, S. J. Warren

We have compiled a sample of $\sim 9600$ bright, $i\le 18.95$, red, $b_j-r>2$, candidate galaxies in an area of 220 deg${}^2$. These are luminous, $L>L^{\ast }$, field early-type galaxie…
