 AA2153  PID         -  AA2153
 AA2153
 AA2153  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 AA2153  at the 95% confidence level per Federal Geographic Data Committee
 AA2153  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 AA2153  the standard deviations (one sigma) of the coordinates (NETWORK) or
 AA2153  of the difference in the coordinates (LOCAL) in latitude, longitude
 AA2153  and ellipsoid height.  CorrNE is the (unitless) correlation
 AA2153  coefficient between the latitude and longitude components of either
 AA2153  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 AA2153  the three-dimensional straight-line slope distance, in km, between
 AA2153  station AA2153 and the corresponding local station.  Local stations
 AA2153  are stations processed simultaneously in a session regardless of
 AA2153  distance.
 AA2153
 AA2153  Accuracy and standard deviation values are given in cm.
