 FX0846  ACCURACIES  -  Complete network and local accuracy information.
 FX0846  CBN         -  This is a Cooperative Base Network Control Station.

 FX0846  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 FX0846  at the 95% confidence level per Federal Geographic Data Committee
 FX0846  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 FX0846  the standard deviations (one sigma) of the coordinates (NETWORK) or
 FX0846  of the difference in the coordinates (LOCAL) in latitude, longitude
 FX0846  and ellipsoid height.  CorrNE is the (unitless) correlation
 FX0846  coefficient between the latitude and longitude components of either
 FX0846  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 FX0846  the three-dimensional straight-line slope distance, in km, between
 FX0846  station FX0846 and the corresponding local station.  Local stations
 FX0846  are stations processed simultaneously in a session regardless of
 FX0846  distance.

 FX0846  Accuracy and standard deviation values are given in cm.
