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.
