A.5 Kinney-Calzetti Atlas


This atlas consists of an homogeneous set of 12 spectral templates of galaxies covering the ultraviolet, optical and near-infrared wavelength range up to about 1 micron. Templates include various morphological types and starburst galaxies. 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.

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 spectra are located in the crgrid$kc96/ directory.
