  Please provide any other information that you feel will be
  helpful in demonstrating your station's capabilities to
  participate in the IVS. If you proposed to the IERS in
  1995/6 as a radio telescope observatory and wish to have
  that proposal carry over to the IVS, please make such a
  statement in this proposal. 
  
  Your signature on this form indicates your agreement to
  participate in the IVS as a Network Station, to comply with
  IVS performance standards for data quality and operational
  reliability, and to work closely with the IVS Network and
  Technology Coordinators. If this is a new proposal (i.e. not
  carried over from IERS) your signature commits your
  organization to participate in the IVS.
