 DL8568
 DL8568  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 DL8568  at the 95% confidence level per Federal Geographic Data Committee
 DL8568  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 DL8568  the standard deviations (one sigma) of the coordinates (NETWORK) or
 DL8568  of the difference in the coordinates (LOCAL) in latitude, longitude
 DL8568  and ellipsoid height.  CorrNE is the (unitless) correlation
 DL8568  coefficient between the latitude and longitude components of either
 DL8568  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 DL8568  the three-dimensional straight-line slope distance, in km, between
 DL8568  station DL8568 and the corresponding local station.  Local stations
 DL8568  are stations processed simultaneously in a session regardless of
 DL8568  distance.
 DL8568
 DL8568  Accuracy and standard deviation values are given in cm.
