Scientific paper

We developed an Integrated-light photometric database in the far (1500 Angstrom) and near (2300 Angstrom) ultraviolet, covering a big data set the Galactic Globular Clusters (GGCs) available in the GALEX GR6 data release. The dataset includes 40 objects, spanning a wide range of stellar population properties. We performed curve of growth and King model fitting on the FUV and NUV images to obtain total magnitudes in these two passbands. Together with existing optical and infrared integrated photometry, age and metallicity estimates available from the literature, this constitutes an important multi-wavelength empirical dataset to compare with unresolved old stellar populations (GCs in distant galaxies). This is the first extension of the integrated-light measurements of old stellar populations in the Far-UV spectral domain. The UV data provide an unique opportunity to test and improve the Simple Stellar Populations (SSP) model performance in this part of the spectrum (e.g. the influence of blue and extreme HB stars and blue stragglers on integrated photometry and spectroscopy).
