A STATISTICAL STUDY OF THE SPECTRA OF VERY LUMINOUS IRAS GALAXIES - I- DATA

This paper presents the results of spectral observations for the large st complete sample of very luminous IRAS galaxies obtained to date. Th e sample consists of those 73 objects for which log(L-IR/L.) greater t han or equal to 11.5 (H-0 = 50 km s(-1) Mpc(-1), q(0) = 0.5) and mag l ess than or equal to 15.5, and was extracted from the 2 Jy IRAS redshi ft catalog. All the spectra were obtained using the 2.16 m telescope o f Beijing Astronomical Observatory during the years 1994-1996. A total of 123 galaxy spectra were obtained with spectral ranges of 4400 Angs trom to 7100 Angstrom and 3500 Angstrom to 8100 Angstrom at resolution s of 11.2 Angstrom and 9.3 Angstrom respectively. In addition to the 7 3 spectra for sample galaxies, we also present spectra for ten non-sam ple galaxies and a further 40 for the companions of sample galaxies, T he data presented include nuclear spectrum and the parameters describi ng the emission lines, absorption lines and continua as well as DSS im ages and environmental parameters(1).
