 AA2158  PID         -  AA2158
 AA2158
 AA2158  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 AA2158  at the 95% confidence level per Federal Geographic Data Committee
 AA2158  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 AA2158  the standard deviations (one sigma) of the coordinates (NETWORK) or
 AA2158  of the difference in the coordinates (LOCAL) in latitude, longitude
 AA2158  and ellipsoid height.  CorrNE is the (unitless) correlation
 AA2158  coefficient between the latitude and longitude components of either
 AA2158  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 AA2158  the three-dimensional straight-line slope distance, in km, between
 AA2158  station AA2158 and the corresponding local station.  Local stations
 AA2158  are stations processed simultaneously in a session regardless of
 AA2158  distance.
 AA2158
 AA2158  Accuracy and standard deviation values are given in cm.
