Two types of time series can be distinguished:

• Residual coordinate time series displaying the residuals of a Helmert transformation between a cumulative coordinate/velocity solution based on the weekly combined EPN solutions and each of the weekly combined EPN solutions:
  • raw time series: coordinate outliers are not eliminated, one coordinate/velocity set for each stations
  • cleaned time series: coordinate outliers are eliminated, a new coordinate/velocity is estimated if necessary
• Coordinate time series displaying the time evolution of the coordinates included in the weekly combined EPN solutions:
  • ITRS time series: coordinates in ITRS extracted from weekly solution as is
  • ETRS time series: coordinates in ITRS extracted from weekly solution and transformed to ETRS89
