  We present the Cassini Atlas Of Stellar Spectra (CAOSS), comprised of
near-infrared low-resolution spectra of bright stars recovered from space-based
observations by the Cassini spacecraft. The 65 stellar targets in the atlas are
predominately M, K and S giants. However it also contains spectra of other
bright nearby stars including carbon stars and main sequence stars from A to F.
The spectra presented are free of all spectral contamination caused by the
Earth's atmosphere, including the detrimental telluric molecular bands which
put parts of the near-infrared spectrum out of reach of terrestrial
observations. With a single instrument, a spectro-photometric dataset is
recovered that spans the near-infrared from 0.8 to 5.1 microns with spectral
resolution ranging from R=53.5 to R=325. Spectra have been calibrated into
absolute flux units after careful characterisation of the instrumental spectral
efficiency. Spectral energy distributions for most stars match closely with
literature values. All final data products have been made available online.
