 DH2915
 DH2915  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 DH2915  at the 95% confidence level per Federal Geographic Data Committee
 DH2915  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 DH2915  the standard deviations (one sigma) of the coordinates (NETWORK) or
 DH2915  of the difference in the coordinates (LOCAL) in latitude, longitude
 DH2915  and ellipsoid height.  CorrNE is the (unitless) correlation
 DH2915  coefficient between the latitude and longitude components of either
 DH2915  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 DH2915  the three-dimensional straight-line slope distance, in km, between
 DH2915  station DH2915 and the corresponding local station.  Local stations
 DH2915  are stations processed simultaneously in a session regardless of
 DH2915  distance.
 DH2915
 DH2915  Accuracy and standard deviation values are given in cm.
