GW1129 ACCURACIES - Complete network and local accuracy information.
GW1129 DESIGNATION - COCKE
GW1129 PID - GW1129
GW1129
GW1129 Horiz and Ellip are the horizontal and ellipsoid height accuracies
GW1129 at the 95% confidence level per Federal Geographic Data Committee
GW1129 Geospatial Positioning Accuracy Standards. SD_N, SD_E and SD_h are
GW1129 the standard deviations (one sigma) of the coordinates (NETWORK) or
GW1129 of the difference in the coordinates (LOCAL) in latitude, longitude
GW1129 and ellipsoid height. CorrNE is the (unitless) correlation
GW1129 coefficient between the latitude and longitude components of either
GW1129 the coordinate (NETWORK) or coordinate difference (LOCAL). Dist is
GW1129 the three-dimensional straight-line slope distance, in km, between
GW1129 station GW1129 and the corresponding local station. Local stations
GW1129 are stations processed simultaneously in a session regardless of
GW1129 distance.

GW1129 Accuracy and standard deviation values are given in cm.
