Abstract:
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☉) is also provided.
