 GM0052  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 GM0052  at the 95% confidence level per Federal Geographic Data Committee
 GM0052  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 GM0052  the standard deviations (one sigma) of the coordinates (NETWORK) or
 GM0052  of the difference in the coordinates (LOCAL) in latitude, longitude
 GM0052  and ellipsoid height.  CorrNE is the (unitless) correlation
 GM0052  coefficient between the latitude and longitude components of either
 GM0052  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 GM0052  the three-dimensional straight-line slope distance, in km, between
 GM0052  station GM0052 and the corresponding local station.  Local stations
 GM0052  are stations processed simultaneously in a session regardless of
 GM0052  distance.

 GM0052  Accuracy and standard deviation values are given in cm.
