A statistical study of the spectra of very luminous IRAS galaxies. I. Data

This paper presents the results of spectral observations for the largest complete sample of very luminous IRAS galaxies obtained to date. The sample consists of those 73 objects for which log(L_IR/L_sun) >= 11.5 (H₀=50;km; s(-1) Mpc(-1) , q₀=0.5) and mag <= 15.5 , and was extracted from the 2 Jy IRAS redshift catalog. All the spectra were obtained using the 2.16 m telescope of Beijing Astronomical Observatory during the years 1994-1996. A total of 123 galaxy spectra were obtained with spectral ranges of 4400;Angstroms to 7100;Angstroms and 3500;Angstroms to 8100;Angstroms at resolutions of 11.2;Angstroms and 9.3;Angstroms respectively. In addition to the 73 spectra for sample galaxies, we also present spectra for ten non-sample galaxies and a further 40 for the companions of sample galaxies. The data presented include nuclear spectrum and the parameters describing the emission lines, absorption lines and continua as well as DSS images and environmental parameters.
