Subject: New tuned ESOC IRVs for Envisat

ESOC have now improved their IRVs by tuning them. The first tuned
IRVs were released on Monday 22nd December. We have monitored the
resulting timebiases for these new tuned IRVs and can confirm that
the tuning appears to be excellent. This means that the timebiases
are continuous from day-to-day and that the timebias function
should be very good.

We would therefore STRONGLY recommend that everybody uses ESOC IRVs
(+timebias function) for Envisat.
