 GA3305
 GA3305  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 GA3305  at the 95% confidence level per Federal Geographic Data Committee
 GA3305  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 GA3305  the standard deviations (one sigma) of the coordinates (NETWORK) or
 GA3305  of the difference in the coordinates (LOCAL) in latitude, longitude
 GA3305  and ellipsoid height.  CorrNE is the (unitless) correlation
 GA3305  coefficient between the latitude and longitude components of either
 GA3305  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 GA3305  the three-dimensional straight-line slope distance, in km, between
 GA3305  station GA3305 and the corresponding local station.  Local stations
 GA3305  are stations processed simultaneously in a session regardless of
 GA3305  distance.

 GA3305  Accuracy and standard deviation values are given in cm.
