 DP5422
 DP5422  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 DP5422  at the 95% confidence level per Federal Geographic Data Committee
 DP5422  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 DP5422  the standard deviations (one sigma) of the coordinates (NETWORK) or
 DP5422  of the difference in the coordinates (LOCAL) in latitude, longitude
 DP5422  and ellipsoid height.  CorrNE is the (unitless) correlation
 DP5422  coefficient between the latitude and longitude components of either
 DP5422  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 DP5422  the three-dimensional straight-line slope distance, in km, between
 DP5422  station DP5422 and the corresponding local station.  Local stations
 DP5422  are stations processed simultaneously in a session regardless of
 DP5422  distance.
 DP5422
 DP5422  Accuracy and standard deviation values are given in cm.
