Station name: pons Lat(dms): 44 10 12.1357 Long(dms): -124 06 59.4209 Height (m): -16.4910 Mean Observation Time: 1997.4818 Position (XYZ m): -2570120.1721 -3793697.0344 4421651.5106 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: -15.22 X: -15.44 E: -11.49 Y: -2.31 U: -0.05 Z: -10.95 Segment: 0 No-of-obs-used: 8 Vel(mm/a) Vel-sig(mm/a) RMS(mm) StdDevObsUnitWt Vel-XYZ(mm/a): N: 8.1 0.8 6.31 1.16 6.0 E: 5.4 1.0 10.54 1.57 -0.7 U: 4.0 2.5 27.16 1.47 8.6 N-E Correlation: -0.0849
