 GV1749
 GV1749  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 GV1749  at the 95% confidence level per Federal Geographic Data Committee
 GV1749  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 GV1749  the standard deviations (one sigma) of the coordinates (NETWORK) or
 GV1749  of the difference in the coordinates (LOCAL) in latitude, longitude
 GV1749  and ellipsoid height.  CorrNE is the (unitless) correlation
 GV1749  coefficient between the latitude and longitude components of either
 GV1749  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 GV1749  the three-dimensional straight-line slope distance, in km, between
 GV1749  station GV1749 and the corresponding local station.  Local stations
 GV1749  are stations processed simultaneously in a session regardless of
 GV1749  distance.
 GV1749
 GV1749  Accuracy and standard deviation values are given in cm.
