The PSCz catalogue

We present the catalogue, mask, redshift data and selection function for th e PSCz survey of 15 411 IRAS galaxies across 84 per cent of the sky. Most o f the IRAS data are taken from the Point Source Catalog, but this has been supplemented and corrected in various ways to improve the completeness and uniformity. We quantify the known imperfections in the catalogue, and we as sess the overall uniformity, completeness and data quality. We find that ov erall the catalogue is complete and uniform to within a few per cent at hig h latitudes and 10 per cent at low latitudes. Ancillary information, access details, guidelines and caveats for using the catalogue are given.
