AA2168 ACCURACIES - Complete network and local accuracy information.
AA2168 DESIGNATION - 2 45
AA2168 PID - AA2168
AA2168
AA2168 Horiz and Ellip are the horizontal and ellipsoid height accuracies
AA2168 at the 95% confidence level per Federal Geographic Data Committee
AA2168 Geospatial Positioning Accuracy Standards. SD_N, SD_E and SD_h are
AA2168 the standard deviations (one sigma) of the coordinates (NETWORK) or
AA2168 of the difference in the coordinates (LOCAL) in latitude, longitude
AA2168 and ellipsoid height. CorrNE is the (unitless) correlation
AA2168 coefficient between the latitude and longitude components of either
AA2168 the coordinate (NETWORK) or coordinate difference (LOCAL). Dist is
AA2168 the three-dimensional straight-line slope distance, in km, between
AA2168 station AA2168 and the corresponding local station. Local stations
AA2168 are stations processed simultaneously in a session regardless of
AA2168 distance.

AA2168 Accuracy and standard deviation values are given in cm.
