 GX0556
 GX0556  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 GX0556  at the 95% confidence level per Federal Geographic Data Committee
 GX0556  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 GX0556  the standard deviations (one sigma) of the coordinates (NETWORK) or
 GX0556  of the difference in the coordinates (LOCAL) in latitude, longitude
 GX0556  and ellipsoid height.  CorrNE is the (unitless) correlation
 GX0556  coefficient between the latitude and longitude components of either
 GX0556  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 GX0556  the three-dimensional straight-line slope distance, in km, between
 GX0556  station GX0556 and the corresponding local station.  Local stations
 GX0556  are stations processed simultaneously in a session regardless of
 GX0556  distance.
 GX0556
 GX0556  Accuracy and standard deviation values are given in cm.
