 AA2157  PID         -  AA2157
 AA2157
 AA2157  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 AA2157  at the 95% confidence level per Federal Geographic Data Committee
 AA2157  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 AA2157  the standard deviations (one sigma) of the coordinates (NETWORK) or
 AA2157  of the difference in the coordinates (LOCAL) in latitude, longitude
 AA2157  and ellipsoid height.  CorrNE is the (unitless) correlation
 AA2157  coefficient between the latitude and longitude components of either
 AA2157  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 AA2157  the three-dimensional straight-line slope distance, in km, between
 AA2157  station AA2157 and the corresponding local station.  Local stations
 AA2157  are stations processed simultaneously in a session regardless of
 AA2157  distance.
 AA2157
 AA2157  Accuracy and standard deviation values are given in cm.
