Notes. Dispersion is 5.52 Å per pixel for FORS1/150I and 2.50 Å per pixel for VIMOS/MR/OS-red. The VIMOS redshifts were obtained from the z-COSMOS follow-up of the field (Lilly et al. 2007, 2009). The Keck/DEIMOS observations were taken with the 830 line/mm grating and using the OG550 blocking filter, which lead to a dispersion of 0.47 Å per pixel. The Keck/LRIS targets were simultaneously observed with both blue grating (300/5000, dispersion: 2.55 Å per pixel) and red grating (600/7500, dispersion: 1.28 Å per pixel) (see Lagattuta et al. 2010).
