Station name: pres Lat(dms): 46 02 24.2530 Long(dms): -122 55 28.3390 Height (m): 340.8761 Mean Observation Time: 1998.3008 Position (XYZ m): -2410764.4665 -3722977.3306 4568585.7167 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: -14.89 X: -15.93 E: -12.06 Y: -2.42 U: -0.05 Z: -10.37 Segment: 0 No-of-obs-used: 4 Vel(mm/a) Vel-sig(mm/a) RMS(mm) StdDevObsUnitWt Vel-XYZ(mm/a): N: 7.1 0.9 3.27 0.90 7.3 E: 4.3 1.1 4.07 0.92 3.4 U: -2.5 2.9 7.15 0.58 3.1 N-E Correlation: -0.0412
