  -----------------
  
  :Author: Julien Woillez (jwoillez@gmail.com)
  
  This package is for querying the VizieR service, primarily hosted at:
  http://vizier.u-strasbg.fr
  
  Note: If the access to catalogues with VizieR was helpful for your research
  work, the following acknowledgment would be appreciated::
  
    This research has made use of the VizieR catalogue access tool, CDS,
    Strasbourg, France.  The original description of the VizieR service was
    published in A&AS 143, 23
