 AA2154  PID         -  AA2154
 AA2154
 AA2154  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 AA2154  at the 95% confidence level per Federal Geographic Data Committee
 AA2154  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 AA2154  the standard deviations (one sigma) of the coordinates (NETWORK) or
 AA2154  of the difference in the coordinates (LOCAL) in latitude, longitude
 AA2154  and ellipsoid height.  CorrNE is the (unitless) correlation
 AA2154  coefficient between the latitude and longitude components of either
 AA2154  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 AA2154  the three-dimensional straight-line slope distance, in km, between
 AA2154  station AA2154 and the corresponding local station.  Local stations
 AA2154  are stations processed simultaneously in a session regardless of
 AA2154  distance.
 AA2154
 AA2154  Accuracy and standard deviation values are given in cm.
