 GL0280
 GL0280  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 GL0280  at the 95% confidence level per Federal Geographic Data Committee
 GL0280  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 GL0280  the standard deviations (one sigma) of the coordinates (NETWORK) or
 GL0280  of the difference in the coordinates (LOCAL) in latitude, longitude
 GL0280  and ellipsoid height.  CorrNE is the (unitless) correlation
 GL0280  coefficient between the latitude and longitude components of either
 GL0280  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 GL0280  the three-dimensional straight-line slope distance, in km, between
 GL0280  station GL0280 and the corresponding local station.  Local stations
 GL0280  are stations processed simultaneously in a session regardless of
 GL0280  distance.
 GL0280
 GL0280  Accuracy and standard deviation values are given in cm.
