J/ApJS/166/498  Atlas of HST STIS spectra of Seyfert galaxies  (Spinelli+, 2006)

An atlas of Hubble space telescope STIS spectra of Seyfert galaxies. Spinelli P.F., Storchi-Bergmann T., Brandt C.H., Calzetti D. <Astrophys. J. Suppl. Ser., 166, 498-504 (2006)> =2006ApJS..166..498S
ADC_Keywords: Galaxies, Seyfert ; Galaxies, spectra Keywords: atlases - galaxies: nuclei - galaxies: Seyfert - ultraviolet: galaxies Abstract: We present a compilation of spectra of 101 Seyfert galaxies obtained with the Hubble Space Telescope (HST) Space Telescope Imaging Spectrograph (STIS), covering the UV and/or optical spectral range. Information on all the available spectra have been collected in a Mastertable, which is a very useful tool for anyone interested in a quick glance at the existent STIS spectra for Seyfert galaxies in the HST archive, and it can be recovered electronically. Nuclear spectra of the galaxies have been extracted in windows of 0.2" for an optimized sampling (as this is the slit width in most cases) and combined in order to improve the signal-to-noise ratio and provide the widest possible wavelength coverage. These combined spectra are also available electronically, at . File Summary:

Note (1): Notes as follows: b = Spectra of this galaxy were not extracted due to a poor signal-to-noise ratio in the continuum. Nevertheless, information on the available spectra is also included in the Mastertable (table2.dat). c = Spectra of this galaxy were not extracted due to the presence of more than one continuum source where we could not identify the brightest one. Information on the available spectra is also included in the Mastertable (table2.dat). d = Final spectrum of this Seyfert 1 galaxy was obtained with spectra observed in different dates.

Note (1): Flag on HST as follows: * = the long slit spectrum has the extension '_x2d' otherwise means extension '_sx2' (LS) = low signal-to-noise ratio, we did not extract a nuclear spectrum in this case # = continuum source is absent, thus we did not extract a nuclear spectrum (2S) = there are two sources, and we did not extract a nuclear spectrum in this case (!) = Warning: this spectrum was combined with another spectra observed in different dates to compile a final Sy1-1.9 galaxy spectrum
