slice-2dF-geometry.jpg and slice-2dF.gif are from the 2dF redshift survey site http://www.mso.anu.edu.au/2dFGRS/ in the image gallery. There are 382323 target objects in the 2dF Galactic Redshift Survey. These are in the photometric catalog. The spectroscopic catalog (includes redshifts) is 245591, so use the 245591 number for the #galaxies in the slice plot. But slide from conference displaying final results says 221,000 unique galaxy redshifts (actually 221414 galaxies)
