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.
