Scientific paper

We present a new catalogue of galaxies in the direction of the Virgo Cluster's core: the Virgo Photometry Catalogue (VPC)*. This catalogue contains 1180 galaxies (including background objects) within a 23 square-degree area of the sky centred on R.A._{1950.0} = 12h 26m and dec._{1950.0} = 13(deg) 08'. The VPC galaxy sample comprises of non-stellar objects brighter than B_J25 = 19.0; the completeness limits being B_J25 ~18.5 for the northern half of the survey area and B_J25 ~18.0 for the southern half. Independently-calibrated photographic surface photometry is presented for over 1000 galaxies in the U, B_J and R_C bands. Parameters listed for catalogued galaxies include: equatorial coordinates, morphological types, surface-brightness profile parameters (which preserve the majority of the original surface photometry information), U, B_J & R_C isophotal magnitudes, B_J and [transformed] B total magnitudes, (U-B_J) and (B_J-R_C) equal-area and total colours, apparent angular radii, ellipticities, position angles, heliocentric radial velocities and alternative designations. All total magnitudes and total colours are extrapolated according to a new system denoted t in order to distinguish it from the T system already in use. The VPC is based primarily on four (one U, two B_J and one R_C) UK-Schmidt plates, all of which were digitised using the Royal Observatory Edinburgh's (ROE) COSMOS measuring machine. All magnitudes, colours and surface-brightness parameters are derived from numerical integrations of segmented plate-scan data, except for (in 109 cases) saturated or (in 51 cases) inextricably-merged images; our segmentation software being able to cope with the vast majority of image mergers. * Appendices B, C and E, which contain the surface photometry, the main catalogue and the summary catalogue respectively, are only available in electronic form. They can be obtained from La Centre des Donees astronomiques de Strasbourg (CDS) via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsweb.u-strasbg.fr/Abstract.html.
