QW0458 ACCURACIES - Complete network and local accuracy information.
QW0458 DESIGNATION - B 564
QW0458 PID - QW0458
QW0458
QW0458 Horiz and Ellip are the horizontal and ellipsoid height accuracies
QW0458 at the 95% confidence level per Federal Geographic Data Committee
QW0458 Geospatial Positioning Accuracy Standards. SD_N, SD_E and SD_h are
QW0458 the standard deviations (one sigma) of the coordinates (NETWORK) or
QW0458 of the difference in the coordinates (LOCAL) in latitude, longitude
QW0458 and ellipsoid height. CorrNE is the (unitless) correlation
QW0458 coefficient between the latitude and longitude components of either
QW0458 the coordinate (NETWORK) or coordinate difference (LOCAL). Dist is
QW0458 the three-dimensional straight-line slope distance, in km, between
QW0458 station QW0458 and the corresponding local station. Local stations
QW0458 are stations processed simultaneously in a session regardless of
QW0458 distance.

QW0458 Accuracy and standard deviation values are given in cm.
