   Wei Wenren       Senior engineer, DAT

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. 

  "Seshan station has participated in various international VLBI experiments, 
such as CDP/DOSE and CORE, EVN, APT/APSG, VSOP and others since 1987. It has 
proposed to the IERS in 1995/6 as a radio telescope observatory and wishes to
have that proposal carry over to the IVS."

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.
