 HJ0138  ACCURACIES  -  Complete network and local accuracy information.
 HJ0138  CBN         -  This is a Cooperative Base Network Control Station.
 HJ0138  DESIGNATION -  D 85
 HJ0138  PID         -  HJ0138
 HJ0138
 HJ0138  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 HJ0138  at the 95% confidence level per Federal Geographic Data Committee
 HJ0138  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 HJ0138  the standard deviations (one sigma) of the coordinates (NETWORK) or
 HJ0138  of the difference in the coordinates (LOCAL) in latitude, longitude
 HJ0138  and ellipsoid height.  CorrNE is the (unitless) correlation
 HJ0138  coefficient between the latitude and longitude components of either
 HJ0138  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 HJ0138  the three-dimensional straight-line slope distance, in km, between
 HJ0138  station HJ0138 and the corresponding local station.  Local stations
 HJ0138  are stations processed simultaneously in a session regardless of
 HJ0138  distance.

 HJ0138  Accuracy and standard deviation values are given in cm.
