VizieR Online Data Catalog: 2dF-SDSS Luminous Red Galaxy Survey, 2SLAQ (Cannon+, 2006)
Abstract
This version of the catalogue was created as v5.1 on 01 Feb 2006 by Russell Cannon. Essentially the same data were used in the other 2SLAQ LRG papers written in 2006.
There is one line for each object observed, sorted by RA. The best available redshift, i.e. the one with the highest reliability parameter Q (or the higher S/N in the case of a tie), is given for objects with two or more observations. Another version of the listing, including repeats, is available from the UQ web site at http://lrg.physics.uq.edu.au. The first 27 columns come from the AAO redshifting code (i.e. the concatenated *z.rz output lists from RDC's version of Will Sutherland's original Zcode). Columns 28 to 35 are from the SDSS input target lists prepared by Daniel Eisenstein. Column 36 contains any notes made during the redshifting or subsequent analysis. The first 34 columns are present for all targets, in a fixed format with leading zeroes where appropriate so that they can be easily read in free format. Column 35 gives the original SDSS run_camcol object names for the 2003 2dF data only and is blank otherwise. Note that this version of the redshift listing uses SDSS DR4 photometry in col. 8 and cols. 31-34 (for all but 10 objects) but retains the original DR1 SDSS positions (as used by 2dF) in cols. 28 and 29. Earlier listings up to and including v4 (available from RDC) gave the DR1 photometry used for 2dF target selection; the differences are very small for >99% of the targets.
