Station name: thre Lat(dms): 47 06 09.0114 Long(dms): -122 17 23.2694 Height (m): 140.5112 Mean Observation Time: 1998.7288 Position (XYZ m): -2323479.9920 -3676831.3754 4649631.9533 Reference Frame Information: Note: Final Station velocities are in a North America fixed reference frame derived from ITRF97 (NuvelNNR1A) by: 1) Finding the pole that best fits ITRF97 velocities for ALGO,BRMU,CHUR,DRAO,GODE,KELY,MDO1,NLIB,RCM5,STJO,THU1,WES2,YELL (-2.2012+/-0.9, -79.9603+/-0.4, 0.19676+/-0.0030) 2) Subtracting the predicted motions of 51 itrf Stations about that pole from itrf97. 3) Transforming (7 parameter Helmert) each observed solution into the reference frame defined above. To convert velocities given below back to itrf97 (NuvelNNR1A) add (mm/a): N: -14.71 X: -16.20 E: -12.37 Y: -2.48 U: -0.05 Z: -10.05 Segment: 0 No-of-obs-used: 6 Vel(mm/a) Vel-sig(mm/a) RMS(mm) StdDevObsUnitWt Vel-XYZ(mm/a): N: 5.7 1.4 4.53 1.04 7.8 E: 4.0 1.8 4.76 0.96 4.8 U: -6.0 4.5 10.97 0.78 -0.5 N-E Correlation: -0.0261
