TReCS spectra of nearby active galaxies.
In May
2004, 8-13um spectra of a small number of bright nearby AGN were obtained
with TReCS on Gemini-S. These data have been published in papers
describing the spatially resolved structure of Circinus (Roche et al 2006a:
MNRAS 367, 1689) and the silicate profile in other nearby galaxies with spectra
of NGC 5506, NGC 3094 and NGC 7172 (Roche et al 2006b: astro-ph/0610583).
The text files of the individual spectra can be downloaded below. See the
above papers for details of the instrument set-up and plots of the spectra.
The text files have 4 columns:
1. Wavelength
(in microns),
2. Flux Fl
in (10-20 Wcm-2),
3. estimated
error (derived from the scatter in the points),
4. best fit
using black body emission and silicate absorption (+PAH emission in the outer
regions of Circinus)
