The PSCz catalogue

We present the catalogue, mask, redshift data and selection function for the PSCz survey of 15411 IRAS galaxies across 84per cent of the sky. Most of 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 assess the overall uniformity, completeness and data quality. We find that overall the catalogue is complete and uniform to within a few per cent at high latitudes and 10per cent at low latitudes. Ancillary information, access details, guidelines and caveats for using the catalogue are given.
