The MkIV Upgrade Project

J.D. Bregman reported that the MkIV upgrade had been given the go-ahead by the EVN directors. There had been a recent meeting of the upgrade team to get things started. The MkIV correlator chip would be used in several correlators. It had a huge capacity ( VLBA correlator). However, the JIVE correlator would not become available until 1997. Hopefully the VLBA correlator would be running in ``production mode'' by the end of this year/beginning of next year. The VLBA and the VLBA correlator would set new standards which the EVN could not afford to ignore. It would no longer be possible to continue doing VLBI on a ``best efforts'' basis - we would have to do better than that and adhere to standards. Antenna logs/calibration would have to be in a format that could be read by the VLBA correlator. Recorded tapes would have to be shipped to the VLBA correlator on a weekly basis, rather than at the end of an observing session. More manpower/support would be required for VLBI at each of the EVN stations. M.A. Garrett noted that logs would also have to be sent via ftp on a similar time-scale.
