 BN0260  ACCURACIES  -  Complete network and local accuracy information.
 BN0260  SACS        -  This is a Secondary Airport Control Station.
 BN0260  DESIGNATION -  U 120
 BN0260  PID         -  BN0260

 BN0260  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 BN0260  at the 95% confidence level per Federal Geographic Data Committee
 BN0260  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 BN0260  the standard deviations (one sigma) of the coordinates (NETWORK) or
 BN0260  of the difference in the coordinates (LOCAL) in latitude, longitude
 BN0260  and ellipsoid height.  CorrNE is the (unitless) correlation
 BN0260  coefficient between the latitude and longitude components of either
 BN0260  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 BN0260  the three-dimensional straight-line slope distance, in km, between
 BN0260  station BN0260 and the corresponding local station.  Local stations
 BN0260  are stations processed simultaneously in a session regardless of
 BN0260  distance.

 BN0260  Accuracy and standard deviation values are given in cm.
