Since June 30, GPS solutions are referred to ITRF94. In order to avoid discontinuities in the current combined solutions, all series have been referred back to ITRF93 system. Analyses of the next Bulletin B103 will take into account series in the ITRF94 system. For complete list of data, see Bulletin B in section 7. Units : 0.001" for x,y , 0.0001s for UT1, 0.001" for dPsi, dEpsi. -------------------------------------------------------------------------------- EOP series Mean formal uncertainty Periods covered Weighted RMS agreement with Bulletin B -------------------------------------------------------------------------------- Data x y UT dPsi dEps Number VLBI EOP(JPL) 96 R 01 Au-Ca - - 1.21 - - 7 50238.28 to 50287.98 - - 0.86 - - EOP(JPL) 96 R 01 Sp-Ca - - 0.68 - - 9 50235.83 to 50291.46 - - 0.70 - - EOP(IAA) 96 R 03 0.14 0.11 0.07 0.25 0.11 6 50239.25 to 50288.25 0.14 0.23 0.12 0.39 0.07 EOP(IAA) 96 R 04 - - 0.28 - - 34 50237.73 to 50291.88 - - 0.72 - - EOP(USNO) 96 R 04 0.16 0.14 0.10 0.20 0.09 8 50239.25 to 50281.25 0.29 0.20 0.07 0.17 0.06 EOP(USNO) 96 R 05 - - 0.24 - - 39 50237.73 to 50291.87 - - 0.10 - - LLR EOP(UTXMO)96 M 01 Cerga - - 1.43 - - 7 50242.12 to 50274.24 - - 0.44 - - EOP(UTXMO)96 M 01 TLRS - - 2.88 - - 12 50239.44 to 50291.19 - - 1.42 - - GPS EOP(CODE) 95 P 01 0.02 0.02 - - - 60 50235.50 to 50294.50 0.20 0.20 - - - EOP(EMR) 95 P 01 0.07 0.08 - - - 57 50235.50 to 50291.50 0.29 0.27 - - - EOP(ESOC) 95 P 01 0.05 0.06 - - - 50 50235.50 to 50284.50 0.19 0.29 - - - EOP(GFZ) 95 P 01 0.01 0.01 - - - 50 50235.50 to 50284.50 0.14 0.16 - - - EOP(JPL) 95 P 01 0.03 0.04 - - - 57 50235.50 to 50291.50 0.15 0.16 - - - EOP(NOAA) 95 P 02 0.02 0.03 - - - 51 50235.50 to 50284.50 0.26 0.47 - - - EOP(SIO) 95 P 01 0.08 0.09 - - - 50 50235.50 to 50284.50 0.20 0.21 - - - EOP(IGS) 95 P 01 0.09 0.16 - - - 43 50235.50 to 50277.50 0.12 0.12 - - - EOP(IERS) 95 P 01 0.09 0.11 0.40 - - 60 50235.50 to 50294.50 0.11 0.09 0.43 - - EOP(IGS) 96 P 01 0.14 0.24 - - - 45 50235.50 to 50284.50 0.22 0.20 - - - SLR EOP(CSR) 95 L 01 0.36 0.37 0.64 - - 19 50238.20 to 50291.51 0.19 0.13 0.47 - - EOP(DUT) 93 L 03 0.13 0.12 - - - 19 50235.00 to 50289.00 0.45 0.40 - - - EOP(IAA) 96 L 02 0.18 0.17 0.50 - - 60 50235.00 to 50294.00 0.44 0.33 1.16 - - EOP(MCC) 96 L 01 0.09 0.09 - - - 19 50235.00 to 50289.00 0.36 0.37 - - - [Mailed From: "Lucette Castrique, Paris Observatory, 40 51 22 28"]
