Last changes in the time series data analysis: Week 678 = 93003 : See DORISMail #0288, start of the time series Week 1281 = 04207 : Estimate DORIS wet tropospheric delay per measurement using a randomwalk approch (Psigma = 5 cm per day) no horizontal gradients used yet. See DORISMail #0345 Week 1287 = 04249 : Start using cumulative solution ign04d02 to perform the ITRF2000 transformation (when needed) Week 1293 = 04291 : Start using actual mass information for all satellites (as provided in the new *mass.txt files) instead of nominal values as before 4) Global Statistics ==================== GPS week number 1338 from 28-08-2005 to 03-09-2005 Total number of stations = 48 Total number of satellites = 4 Combinations (daily to weekly) CHI2 / DOF = 7.77 The following table only counts DORIS data that have passed CNES preprocesing step Individual daily DORIS
