LW5580 ACCURACIES - Complete network and local accuracy information.
LW5580 DESIGNATION - TENROD 2
LW5580 PID - LW5580
LW5580
LW5580 Horiz and Ellip are the horizontal and ellipsoid height accuracies
LW5580 at the 95% confidence level per Federal Geographic Data Committee
LW5580 Geospatial Positioning Accuracy Standards. SD_N, SD_E and SD_h are
LW5580 the standard deviations (one sigma) of the coordinates (NETWORK) or
LW5580 of the difference in the coordinates (LOCAL) in latitude, longitude
LW5580 and ellipsoid height. CorrNE is the (unitless) correlation
LW5580 coefficient between the latitude and longitude components of either
LW5580 the coordinate (NETWORK) or coordinate difference (LOCAL). Dist is
LW5580 the three-dimensional straight-line slope distance, in km, between
LW5580 station LW5580 and the corresponding local station. Local stations
LW5580 are stations processed simultaneously in a session regardless of
LW5580 distance.

LW5580 Accuracy and standard deviation values are given in cm.
