 AH8407
 AH8407  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 AH8407  at the 95% confidence level per Federal Geographic Data Committee
 AH8407  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 AH8407  the standard deviations (one sigma) of the coordinates (NETWORK) or
 AH8407  of the difference in the coordinates (LOCAL) in latitude, longitude
 AH8407  and ellipsoid height.  CorrNE is the (unitless) correlation
 AH8407  coefficient between the latitude and longitude components of either
 AH8407  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 AH8407  the three-dimensional straight-line slope distance, in km, between
 AH8407  station AH8407 and the corresponding local station.  Local stations
 AH8407  are stations processed simultaneously in a session regardless of
 AH8407  distance.
 AH8407
 AH8407  Accuracy and standard deviation values are given in cm.
