Beginning of ReadMe : VII/141 Spectrophotometric Atlas of Galaxies (Kennicutt Jr. 1992) ================================================================================ A Spectrophotometric Atlas of Galaxies Kennicutt Jr. R.C. <Astrophys. J. Suppl. Ser. 79, 255 (1992)> =1992ApJS...79..255K ================================================================================ ADC_Keywords: Galaxies, nearby; Galaxies, spectra; Spectrophotometry Description: This catalog contains 56 spectra: 55 galaxy spectra, and one night sky spectrum, which is included for users wishing to check for low-level spurious features in the galaxy spectra. The file "spectra.dat" contains a summary of the spectra. The user should consult the paper for details of the observations and a discussion of the limitations of the spectrophotometry. The spectra are integrated measurements made with apertures comparable to the diameters of the galaxies. The original spectra have been combined, rebinned to a common wavelength scale, and normalized in flux to unity at a reference wavelength of 555nm. An atmospheric extinction correction has been applied to the data, but otherwise they are not corrected for reddening, redshift, etc. The spectral range covered is 365-710 nm and the resolution is 5-8AA. Each spectrum consists in 1726 normalized flux values spaced each 2AA, stored as a file in the subdirectory "sp". Tests show that the spectrophotometry is accurate to the few percent level over small wavelength regions, and at the 10% level over the entire wavelength range. Although the data are useful for a variety of applications, the user should be forewarned that they may not be suitable for applications requiring precision colors over a long wavelength baseline (e.g., computation of K-corrections, some spectral synthesis applications).
