Abstract:
The Millennium Galaxy Catalogue (MGC) is a 37.5deg^2^, medium-deep,
B-band imaging survey along the celestial equator, taken with the Wide
Field Camera on the Isaac Newton Telescope. The survey region is
contained within the regions of both the Two Degree Field Galaxy
Redshift Survey (2dFGRS) and the Sloan Digital Sky Survey Early Data
Release (SDSS-EDR). The survey has a uniform isophotal detection limit
of 26mag.arcsec^-2^ and it provides a robust, well-defined catalogue
of stars and galaxies in the range 16<=B_MGC_<24 mag.
Here we describe the survey strategy, the photometric and astrometric
calibration, source detection and analysis, and present the galaxy
number counts that connect the bright and faint galaxy populations
within a single survey. We argue that these counts represent the state
of the art and use them to constrain the normalizations (phi*) of a
number of recent estimates of the local galaxy luminosity function. We
find that the 2dFGRS, SDSS Commissioning Data (CD), ESO Slice Project,
Century Survey, Durham/UKST, Mt Stromlo/APM, SSRS2 and NOG luminosity
functions require a revision of their published phi* values by
factors of 1.05+/-0.05, 0.76+/-0.10, 1.02+/-0.22, 1.02+/-0.16,
1.16+/-0.28, 1.75+/-0.37, 1.40+/-0.26 and 1.01+/-0.39, respectively.
After renormalizing the galaxy luminosity functions we find a mean
local b_J_ luminosity density of 1.986+/-0.031x10^8^h L_sun_.Mpc^-3^
