THE KINNEY-CALZETTI SPECTRAL ATLAS OF GALAXIES
This atlas contains a set of spectral templates of galaxies covering the ultraviolet to near-infrared spectral range, i.e. from 0.12 up to 1 micron. The ultraviolet range of the spectral templates has been obtained with the large aperture (10" by 20") and low resolution spectrographs of the IUE satellite. The optical spectra were obtained through a long slit with a 10" width, where a window of 20" long was extracted to match the IUE aperture.
The spectral templates cover various galaxy morphological types from elliptical to late type spiral. Starburst templates for low (E(B-V < 0.10) to high (0.61 < E(B-V) < 0.70) internal extinction are also available. Several of the starburst galaxies used in the construction of the starburst templates are classified as irregulars. Thus, although irregular galaxies are not explicitly covered, the starburst templates can be used to cover this morphological type. Details about how the templates have been constructed can be found in Kinney et al. (1996) for the different morphological types, and in Calzetti et al. (1994) for the starbursts.
The flux of the spectral templates has been normalized to a visual magnitude of 12.5 (STMAG system). Details about each individual template can also be found in the header of the STSDAS binary file. The header of a STSDAS file can be read using the tupar task of the IRAF ttools package. STSDAS files can be dumped into an ASCII formatted file using the tdump task of the IRAF ttools package.
