Origin of cable cal data: database content. 6. Application of cable cal flags: database settings. 7. Selection/settings of geophysical models: replace database settings. 7.1 A priori Earth orientation: a. precession/nutation model: IAU2000A precession/nutation model modified using the IAU2006 precession model b. short-period tidal variations in X, Y and UT1 were taken into account in accordance with IERS Conventions 2010 implemented in Calc11.0. c. UT1 and polar motion: usno_finals.erp (http://gemini.gsfc.nasa.gov/solve_save/usno_finals.erp) d. Source positions: A priori coordinates from ICRF2. (Appendix A) 7.2 A priori geophysical models: a. Solid Earth tide: IERS Conventions 2010, p.81-88 b. Ocean loading: TPX07.2 implemented in Calc11.0. c. Pole tide: IERS Conventions 2010. Mean pole coordinates used for computation of pole tide deformation were set to the IERS 2003 Conventions recommended values (Chapter 7, eqns 23a, 23b) implemented in Calc11.0. d. Atmospheric loading: provided by the Goddard VLBI group which are available on the Web at http://gemini.gsfc.nasa.gov/aplo (Petrov & Boy, 2004) e. Antenna thermal deformation: IVS antenna thermal expansion model [Nothnagel 2009] http://vlbi.geod.uni-bonn.de/Analysis/Thermal/antenna-info.txt f. Axis offsets: Taken from: http://lupus.gsfc.nasa.gov/files_IVS-AC/gsfc_itrf2013.axo g. Stations: - A priori positions and velocities from ITRF2014 - Definition of the origin and orientation: No net positions adjustment condition in translation and rotation w.r.t. ITRF2014 for 68 stations (Appendix B). - Constraints for time evolution: No net velocity adjustment condition in translation and rotation w.r.t. ITRF2014 velocity field, for the same 68 stations (Appendix B). 8. Parameterization: a. Earth Orientation: X-pole, Y-pole, UT1, Xdot, Ydot, UT1dot, X-nutation and Y-nutation for each session. Constraints of 45 mas for X-pole, Y-pole and 3 sec for UT1. Constraints of 45 mas/day for Xdot, Ydot and 3 sec/day for UT1. Stronger constraints applied to network with weak geometry. b. Baseline Clocks:As set in initial analysis usually used. c. Source positions: Right ascension and declination as global parameters for 944 sources (Appendix C) and as local parameters for 354 sources (Appendix D). d. Station positions: - Coordinates and velocities for 106 stations as global parameters (Appendix E) and as local parameters for 38 stations (Appendix F). - Reference epoch: 2010.0 - The velocities of the following pairs of stations are constrained to be the same.

Station clocks: second order polynomial plus a continuous piecewise linear function with 60 min interval and rate constraint of 5.0E-14. f. Wet zenith tropospheric delays as 60 min piecewise continuous linear function, with rate constraints of 50 psec/hr g. Troposphere gradients: 6 hours east and north piecewise continuous linear function at all stations, offset constraint 0.5 mm and rate constraint 0.5 mm/day h. Antenna axis offsets estimated for every stations 9. Outlier elimination: about 105% of the sessions have been edited at the CGS, the others use the database settings. 10. Further details a. Data type: Group delays only. b. Data editing: 5 deg elevation cutoff. For each session data are not used if: - stations have less than 8 observations - sources have less than 3 observations - baseline have less than 3 observations c. Data weighting: reweight of the observations are done on a baseline basis [J.Gipson et al. 2008] e. 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. f. Software used: Calc 11.0 SOLVE release 2017.12.05 Note: About 10% of the sessions use a slightly different parameterization tha could concern: - Length of the segments forming the pieciwise continuous linear function of the wet zenith tropospheric delay. - Constraints of EOPs and their rates. -------------------------------------------------------------------------- Appendix A List of 295 sources
