J/MNRAS/308/897 QDOT all-sky IRAS redshift survey (Lawrence+, 1999)
The QDOT all-sky IRAS galaxy redshift survey. Lawrence A., Rowan-Robinson M., Ellis R.S., Frenk C.S., Efstathiou G., Kaiser N., Saunders W., Parry I.R., Xia X., Crawford J. <Mon. Not. R. Astron. Soc. 308, 897 (1999)> =1999MNRAS.308..897L
ADC_Keywords: Galaxies, IR ; Redshifts ; Surveys Keywords: surveys - galaxies: active - galaxies: distances and redshifts - infrared: galaxies 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. File Summary:
