Ries" Subject: BADB performance Content-Type: text/plain; charset="us-ascii" ; format="flowed" X-Virus-Scanned: by amavisd-new at csr.utexas.edu X-Validation-by: laurent.soudarin@cls.fr Analysis of 4 cycles of Topex data indicate that the DORIS data from BADB has a considerably higher noise level than normal. Even after removing the orbit/station error in each pass, the average residual RMS is about 0.57 mm/s. There is some indication of a height error in the coordinates, but this may only be a consequence of the higher noise. Regards, John -- John C.
