 DH2911  PID         -  DH2911
 DH2911
 DH2911  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 DH2911  at the 95% confidence level per Federal Geographic Data Committee
 DH2911  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 DH2911  the standard deviations (one sigma) of the coordinates (NETWORK) or
 DH2911  of the difference in the coordinates (LOCAL) in latitude, longitude
 DH2911  and ellipsoid height.  CorrNE is the (unitless) correlation
 DH2911  coefficient between the latitude and longitude components of either
 DH2911  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 DH2911  the three-dimensional straight-line slope distance, in km, between
 DH2911  station DH2911 and the corresponding local station.  Local stations
 DH2911  are stations processed simultaneously in a session regardless of
 DH2911  distance.

 DH2911  Accuracy and standard deviation values are given in cm.
