 AA8791  ACCURACIES  -  Complete network and local accuracy information.
 AA8791  DESIGNATION -  B94034
 AA8791  PID         -  AA8791
 AA8791
 AA8791  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 AA8791  at the 95% confidence level per Federal Geographic Data Committee
 AA8791  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 AA8791  the standard deviations (one sigma) of the coordinates (NETWORK) or
 AA8791  of the difference in the coordinates (LOCAL) in latitude, longitude
 AA8791  and ellipsoid height.  CorrNE is the (unitless) correlation
 AA8791  coefficient between the latitude and longitude components of either
 AA8791  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 AA8791  the three-dimensional straight-line slope distance, in km, between
 AA8791  station AA8791 and the corresponding local station.  Local stations
 AA8791  are stations processed simultaneously in a session regardless of
 AA8791  distance.

 AA8791  Accuracy and standard deviation values are given in cm.
