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
