Dear colleagues, in order to make the download of files from the IERS Combination Pilot Project easier and to avoid confusions in the future, I have just enabled anonymous logins at our ftp-server. Thus, the link given by Pascal ftp://iers1.bkg.bund.de will work from now on. If there are any objections against the public availability of the files, please let me know. However, I assume that the files should be available to the public. With best regards, Wolfgang Schwegmann __________________________________________ Wolfgang Schwegmann IERS Central Bureau Bundesamt für Kartographie und Geodäsie Federal Agency for Cartography and Geodesy Richard-Strauss-Allee 11 D-60598 Frankfurt am Main Internet: http://www.iers.org Tel: # 49-69-6333-314 Fax: # 49-69-6333-425 Email: schwegmann@iers.org > -----Original Message----- > From: Pascal Willis [mailto:Pascal.R.Willis@jpl.nasa.gov] > Sent: Thursday, July 08, 2004 9:27 PM > To: cpp@iers.org > Subject: DORIS summary files available from IGN/JPL Analysis Center > > > Dear colleagues, > > for your information, the IGN/JPL IDS Analysis Center has started to > distribute weekly DORIS summary reports to give all > statistical information > on the DORIS weekly sinex solutions. > > Thanks to Carey Noll and Wolfgang Schwegmann, the recent files are > presently available at IERS ftp site. > > The current naming convention has been derived from the > current sinex naming > convention.
