 AA2168  PID         -  AA2168
 AA2168
 AA2168  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 AA2168  at the 95% confidence level per Federal Geographic Data Committee
 AA2168  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 AA2168  the standard deviations (one sigma) of the coordinates (NETWORK) or
 AA2168  of the difference in the coordinates (LOCAL) in latitude, longitude
 AA2168  and ellipsoid height.  CorrNE is the (unitless) correlation
 AA2168  coefficient between the latitude and longitude components of either
 AA2168  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 AA2168  the three-dimensional straight-line slope distance, in km, between
 AA2168  station AA2168 and the corresponding local station.  Local stations
 AA2168  are stations processed simultaneously in a session regardless of
 AA2168  distance.
 AA2168
 AA2168  Accuracy and standard deviation values are given in cm.
