Abstract:
    Current stellar population models have arguably the largest
    uncertainties in the near-IR wavelength range, partly due to a lack of
    large and well calibrated empirical spectral libraries. In this paper
    we present a project whose aim it is to provide the first library of
    luminosity weighted integrated near-IR spectra of globular clusters 
    to be used to test the current stellar population models and serve 
    as calibrators for future ones. Our pilot study presents spatially
    integrated K-band spectra of three old (≥10Gyr) and metal poor
    ([Fe/H]~-1.4), and three intermediate age (1-2Gyr) and more metal
    rich ([Fe/H]~-0.4) globular clusters in the LMC.

Description:
    Provided are spatially integrated K-band spectra of LMC globular
    clusters in the wavelength range 1.92-2.45 microns. The spectra are
    obtained using the IFU spectrograph SINFONI mounted on the VLT. A
    detailed description of the integration process can be found in the
    paper.
