Can each data center contact please respond to this email with your opinion as to when you will be ready to accept the new version into your operations, thus providing the data in the "normal" data stream? We would like to try to get the new format into operations by the end of 2006. Thank you, Carey. ----- Begin forwarded message: > From: gend@gfz-potsdam.de > Date: November 14, 2006 1:48:27 AM EST > To: IGS AC -- igsacc AAA , AC_CODE -- Rolf > Dach , igsauto@aiub.unibe.ch, Stefan > Schaer , AC_EMR -- Caroline Huot > , Brian Donahue , > Pierre Tetreault , Yves Mireault > , Remi Ferland > , AC_ESA -- Carlos Garcia-Martinez > , Filipe Lopes-Pereira > , Ignacio Romero > , Ignacio Romero , > Tim Springer , Javier Tegedor > , AC_GFZ -- Gerda Beeskow potsdam.de>, Maorong Ge , Waltraud Sommerfeld > , AC_GOPE , AC_JPL -- Brian > Newport , Yvonne Vigue > , AC_MIT -- Tom Herring > , Simon McClusky , Bob King > , AC_NGS -- Bob Dulaney , > Jake Griffiths , William Kass > , "Gerald L.
