Galaxies: Ir, Redshifts, Surveys

Scientific paper

The catalogue from the QDOT survey consists of infrared properties and redshifts of an all-sky sample of 2387 IRAS galaxies brighter than the IRAS PSC 60μm completeness limit (S60>0.6Jy), sparsely sampled at a rate of one-in-six. At |b|>10°, after removing a small number of Galactic sources, the redshift completeness is better than 98% (2086/2127). New redshifts for 1401 IRAS sources were obtained in 1985-88 at several telescopes (see "Note (8)" below) to complete the catalogue; the measurement and reduction of these are described, and the new redshifts tabulated here. We also tabulate all sources at |b|>10° with no redshift so far, and sources with conflicting alternative redshifts either from our own work, or from published velocities. A list of 95 ultraluminous galaxies (i.e. with L(60μm)>1012L&sun;) is also provided.
