Abstract:
This atlas composed by more than 1500 spectra of late-type stars
(spectral types from G to M) observed simultaneously in the optical
and Calcium Triplet spectral ranges. These spectra were obtained as
part of a survey to search for cool supergiants in the Magellanic
Clouds and taken over four epochs. We provide the spectral and
luminosity classification for each spectrum (71% are supergiants, 13%
are giants or luminous giants, 4% are Carbon or S∼Stars and the
remaining 12% are foreground stars of lesser luminosities).
Description:
The data was observed with AAOmega simultaneously in both, optical and
infrared spectral ranges in multiple epochs. Details about of the
gratings used in each epoch are detailed in the paper.

Note (1): The spectra file nane, in subdirectory sp, are
Year/Field/optical/Fibre.dat and Year/Field/infrared/Fibre.dat .
Note (2): Name correspond to those already published in Gonzalez-Fernandez
et al., 2015, Cat. J/A+A/578/A3 ([GDN2015] SMCNNN and [GDN2015] LMCNNN in
Simbad) while Fibre correspond to the name of the spectra available.
Also take into account, that several different fibres (from different fields)
can be assigned to the same target (Name), if this object was observed more
than once. Finally, remember that for each fibre, there are two spectra,
one from the red arm and one from the blue arm.
