Abstract:
We present a panoramic atlas of Spitzer/Infrared Spectrograph (IRS)
spectra of extragalactic sources collected from the recent literature,
with value-added measurements of their spectral features obtained in a
homogeneous and concise manner. The atlas covers the full spectrum of
the extragalactic Universe and includes star-forming galaxies,
obscured and unobscured active galaxies, luminous and ultra-luminous
infrared galaxies, and hybrid objects. Measured features such as the
polycyclic aromatic hydrocarbons, the strength of the silicates in
emission or absorption around 9.7um, rest-frame monochromatic
luminosities or colours, combined with measurements derived from
spectral decomposition are used to establish diagnostics that allow
for classification of sources, based on their infrared properties
alone. Average templates of the various classes are also derived. The
full atlas with the value-added measurements and ancillary archival
data are publicly available at http://www.denebola.org/atlas, with
full references to the original data.

Note (1): The "three-band" colour index, C7-10-14, is defined as
C7-10-14=-2.5log[sqrt(F(7.0)*F(14)))/F(10)]
Note (2): Flags for Silicate features:
-7 = ERROR: too many bad fits in Monte-Carlo simulation
-5 = ERROR: continuum below zero in at least one of reference regions
for interpolation
-4 = ERROR: not enough spectral coverage to estimate continuum
-3 = ERROR: the peak wavelength is not observed
-2 = ERROR: too poor sampling of the silicate feature
0 = SUCCESS: all OK
1 = WARNING: the silicate feature is partially observed.
Flux estimates will be biased.
2 = WARNING: small wavelength coverage forced continuum estimation
very close to the feature
Note (3): Flags for PAH fitting:
-1 = ERROR: insufficient spectral coverage
0 = SUCCESS: all OK
1 = WARNING: estimated underlying continuum is negative
2 = WARNING: estimated PAH flux is negative
3 = WARNING: both continuum and PAH flux estimates are negative
Note (4): when negative, the absolute value represents the flux 5σ
upper limit (in this case, the value of the flux is zero)
