Scientific paper

Previously published data related to 20 papers and various unpublished spectra have been compiled in this library, which contains individual stars, Galactic, M31, and Magellanic Clouds star clusters, and galaxies of various morphological types. Average template spectra built from the individual ones are also provided. Templates of star clusters and early-type galaxies, also included in the present database, were previously published in the AAS CD-ROM Series, Vol. 7 (Leitherer et al., 1996PASP..108..996L). Given the number of objects with similar properties, the template spectra have improved signal to noise and have been built from linked individual spectra in order to cover the whole spectral range from the UV to the near-IR, which is not the case for every particular object. For example, the globular cluster NGC6517 has been observed just in the optical and so contributes to the cluster template G5, the most metal-poor one, only in the corresponding wavelength range; on the other hand, NGC5024, contributes to the same template over the whole wavelength range, from the UV to the near-IR. Being independent observations, data for a given individual object in different spectral ranges are provided separately. The spectra were corrected for foreground reddening (except where indicated otherwise) and their resolution is in the range 3-23A in the spectral domain 1200-10200A. The fluxes (J.s{-1}.m{-2}.nm^{-1}) are normalized to 1 at 5870A. Whenever this wavelength is outside the observed spectral range, normalization was applied at 4000A for UV spectra and 7000A for near-IR spectra (except where indicated otherwise).
