 NB2124  ACCURACIES  -  Complete network and local accuracy information.
 NB2124  CBN         -  This is a Cooperative Base Network Control Station.

 NB2124  PID         -  NB2124
 NB2124
 NB2124  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 NB2124  at the 95% confidence level per Federal Geographic Data Committee
 NB2124  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 NB2124  the standard deviations (one sigma) of the coordinates (NETWORK) or
 NB2124  of the difference in the coordinates (LOCAL) in latitude, longitude
 NB2124  and ellipsoid height.  CorrNE is the (unitless) correlation
 NB2124  coefficient between the latitude and longitude components of either
 NB2124  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 NB2124  the three-dimensional straight-line slope distance, in km, between
 NB2124  station NB2124 and the corresponding local station.  Local stations
 NB2124  are stations processed simultaneously in a session regardless of
 NB2124  distance.

 NB2124  Accuracy and standard deviation values are given in cm.
