 AI8592  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 AI8592  at the 95% confidence level per Federal Geographic Data Committee
 AI8592  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 AI8592  the standard deviations (one sigma) of the coordinates (NETWORK) or
 AI8592  of the difference in the coordinates (LOCAL) in latitude, longitude
 AI8592  and ellipsoid height.  CorrNE is the (unitless) correlation
 AI8592  coefficient between the latitude and longitude components of either
 AI8592  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 AI8592  the three-dimensional straight-line slope distance, in km, between
 AI8592  station AI8592 and the corresponding local station.  Local stations
 AI8592  are stations processed simultaneously in a session regardless of
 AI8592  distance.

 AI8592  Accuracy and standard deviation values are given in cm.
