 BG0421  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 BG0421  at the 95% confidence level per Federal Geographic Data Committee
 BG0421  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 BG0421  the standard deviations (one sigma) of the coordinates (NETWORK) or
 BG0421  of the difference in the coordinates (LOCAL) in latitude, longitude
 BG0421  and ellipsoid height.  CorrNE is the (unitless) correlation
 BG0421  coefficient between the latitude and longitude components of either
 BG0421  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 BG0421  the three-dimensional straight-line slope distance, in km, between
 BG0421  station BG0421 and the corresponding local station.  Local stations
 BG0421  are stations processed simultaneously in a session regardless of
 BG0421  distance.
 BG0421
 BG0421  Accuracy and standard deviation values are given in cm.
