Abstract:
We have developed an automatic technique to search for
low-surface-brightness (LSB) galaxies in the local Universe
(v≤5000km/s) using the automated plate measuring (APM) scan data
of UK Schmidt photographic plates. We optimized our technique and
selection criteria by surveying the known LSB galaxies in the Fornax
cluster. Plate-to-plate magnitude calibrations were carried out using
independent CCD sequences. The galaxies we detected are brighter
than 20Bmag, have scalesizes greater than 3arcsec and a central
surface brightness fainter than 22.5mag/arcsec2. In total 2435 LSB
galaxies were detected over a total area of 2187deg2. The survey
covers the Fornax cluster, NGC 1400, Sculptor and Dorado groups
and the field between. We detect on average 32 LSB galaxies per
5.8°x5.8° field. We have estimated the background (v>5000km/s)
contamination in three ways: by numerical modelling, using a limited
redshift sample and comparing our Fornax data with those of
Ferguson. The results indicate a contamination of about 19 galaxies
per field.
