${session.getAttribute("locale")} 5 The 2dF Galaxy Redshift Survey: the bJ-band galaxy luminosity function and survey selection function MbJ -5log10 h > -22, the luminosity function is accurately described by a Schechter function with M*bJ -5 log10 h = -19.66 ± 0.07, α = -1.21 ± 0.03 and Φ* = (1.61 ± 0.08) × 10-2 h3 Mpc-3, giving an integrated luminosity density of ρL = (1.82 ± 0.17) × 108 h L⊙ Mpc-3 (assuming an Ω0 = 0.3, Λ0 = 0.7 cosmology). The quoted errors have contributions from the accuracy of the photometric zero-point, from large-scale structure in the galaxy distribution and, importantly, from the uncertainty in the appropriate evolutionary corrections. Our luminosity function is in excellent agreement with, but has much smaller statistical errors than, an estimate from the Sloan Digital Sky Survey (SDSS) data when the SDSS data are accurately translated to the bJ band and the luminosity functions are normalized in the same way. We use the luminosity function, along with maps describing the redshift completeness of the current 2dFGRS catalogue, and its weak dependence on apparent magnitude, to define a complete description of the 2dFGRS selection function. Details and tests of the calibration of the 2dFGRS photometric parent catalogue are also presented.]]> Fri 08 Apr 2011 19:52:41 EST ]]>
