Abstract:
    We present results from ground based VLT/FLAMES spectroscopy in
    combination with HST data for the globular cluster NGC 2808. The aim
    of this work is to probe whether this massive cluster hosts an
    intermediate-mass black hole at its center and to compare the results
    with the expected value predicted by the MBH-σ scaling
    relation.

Description:
    We matched the reconstructed ARGUS pointings with the HST image and
    created a combined ARGUS cube. The first two dimensions are measured
    in RA and DEC and the third dimension in wavelength (nm). A header
    with the most important keywords is also given.
