 GW1042  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 GW1042  at the 95% confidence level per Federal Geographic Data Committee
 GW1042  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 GW1042  the standard deviations (one sigma) of the coordinates (NETWORK) or
 GW1042  of the difference in the coordinates (LOCAL) in latitude, longitude
 GW1042  and ellipsoid height.  CorrNE is the (unitless) correlation
 GW1042  coefficient between the latitude and longitude components of either
 GW1042  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 GW1042  the three-dimensional straight-line slope distance, in km, between
 GW1042  station GW1042 and the corresponding local station.  Local stations
 GW1042  are stations processed simultaneously in a session regardless of
 GW1042  distance.

 GW1042  Accuracy and standard deviation values are given in cm.
