Troposphere gradients: 6 hours east and north piecewise continuous linear function, at all stations, except a set of 75 stations (Appendix G) offset constraint 0.5 mm and rate constraint 2.0 mm/day h. Antenna axis offsets: estimated for 84 stations (Appendix H) as global parameters. 9. Outlier elimination: database settings. 10. Further details 10.1. Data type: group delays. 10.2. Data editing: 5 degree elevation cutoff. 10.3. Data weighting: weights are defined as follows: 1/sqrt ( f**2 + a**2 ) where "f" is the formal uncertainty of the ionosphere free linear combination of group delays at X- and S-band obtained by fringe fitting on the base of achieved signal to noise ratio. Station-dependent parameter "a" was computed for each session by an iterative procedure such that the ratio of the sum of squares of the weighted residuals to the estimate of their mathematical expectation is about unity. 10.4. Standard errors reported: all errors are derived from least-squares estimation propagated from the data weights and the constraints applied to the troposphere, clock and EOP parameters. 10.5.
