Abstract:
    The ObsCore VizieR table gather FITS images, spectra and time-series into a 
    single table. The contents are the VizieR associated data, publilished in 
    original article with the tables. 
    The metadata comes from the ObsCore Data Model. ObsCore (Tody et al. 2011) 
    is a standard of the Virtual Observatory used to map images,spectra or 
    time-series resources with standardized metadata.
