Dear colleagues,

as announced in my previous email, several IGN/JPL weekly solutions 
were recently resubmitted.

Changes are expected to be small but it is recommended that all users 
download these new solutions.

A complete list of resubmitted files is available in the latest DORIS 
Report (see http://www.20kmparis.com/web/home.asp).

I would also like to point out that it is important for users to use 
proper citation in peer-reviewed articles.

One more time, here are the recommended references for the IGN/JPL 
DORIS results:

     P. Willis, M. Heflin, External validation of the GRACE GGM01C 
     Gravity Field using GPS and DORIS positioning results, Geophys 
     Res Lett, 31, 13, L13616, doi:10.1029/2004GL020038, 2004.

     P. Willis, C. Boucher, H. Fagard, Z. Altamimi, Applications 
     géodésiques du système DORIS à l'IGN, Geodetic applications of 
     the DORIS system at the French Institut Geographique National, 
     C.R. Geoscience, 337(7), 653-662, 2005, 
     DOI: 10.1016/j.crte.2005.03.002.

The same comment applies for references to IDS. Here are some recent 
publications that can be used for citation:

     Tavernier, G; Soudarin, L; Larson, K; Noll, C; Ries, J; Willis, P. 
     2002. Current status of the DORIS Pilot Experiment and the future 
     international DORIS Service. NEW TRENDS IN SPACE GEODESY, Adv 
     Space Res., 30 (2): 151-156.

     G. Tavernier, H. Fagard, M. Feissel-Vernier, F. Lemoine, C. Noll, 
     L. Soudarin, P. Willis, The International DORIS Service (IDS), 
     Adv. Space Res., 2005, in press, DOI:10.1016/j.asr.2005.03.102
