The WAGGS project - I. The WiFeS Atlas of Galactic Globular cluster
  Spectra
  We present the WiFeS Atlas of Galactic Globular cluster Spectra, a library of
integrated spectra of Milky Way and Local Group globular clusters. We used the
WiFeS integral field spectrograph on the Australian National University 2.3 m
telescope to observe the central regions of 64 Milky Way globular clusters and
22 globular clusters hosted by the Milky Way's low mass satellite galaxies. The
spectra have wider wavelength coverage (3300 {\AA} to 9050 {\AA}) and higher
spectral resolution (R = 6800) than existing spectral libraries of Milky Way
globular clusters. By including Large and Small Magellanic Cloud star clusters,
we extend the coverage of parameter space of existing libraries towards young
and intermediate ages. While testing stellar population synthesis models and
analysis techniques is the main aim of this library, the observations may also
further our understanding of the stellar populations of Local Group globular
clusters and make possible the direct comparison of extragalactic globular
cluster integrated light observations with well understood globular clusters in
the Milky Way. The integrated spectra are publicly available via the project
website.
