FA1448 ACCURACIES - Complete network and local accuracy information.
FA1448 DESIGNATION - W 199
FA1448 PID - FA1448
FA1448
FA1448 Horiz and Ellip are the horizontal and ellipsoid height accuracies
FA1448 at the 95% confidence level per Federal Geographic Data Committee
FA1448 Geospatial Positioning Accuracy Standards. SD_N, SD_E and SD_h are
FA1448 the standard deviations (one sigma) of the coordinates (NETWORK) or
FA1448 of the difference in the coordinates (LOCAL) in latitude, longitude
FA1448 and ellipsoid height. CorrNE is the (unitless) correlation
FA1448 coefficient between the latitude and longitude components of either
FA1448 the coordinate (NETWORK) or coordinate difference (LOCAL). Dist is
FA1448 the three-dimensional straight-line slope distance, in km, between
FA1448 station FA1448 and the corresponding local station. Local stations
FA1448 are stations processed simultaneously in a session regardless of
FA1448 distance.

FA1448 Accuracy and standard deviation values are given in cm.
