 PY1050  ACCURACIES  -  Complete network and local accuracy information.
 PY1050  CBN         -  This is a Cooperative Base Network Control Station.

 PY1050
 PY1050  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 PY1050  at the 95% confidence level per Federal Geographic Data Committee
 PY1050  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 PY1050  the standard deviations (one sigma) of the coordinates (NETWORK) or
 PY1050  of the difference in the coordinates (LOCAL) in latitude, longitude
 PY1050  and ellipsoid height.  CorrNE is the (unitless) correlation
 PY1050  coefficient between the latitude and longitude components of either
 PY1050  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 PY1050  the three-dimensional straight-line slope distance, in km, between
 PY1050  station PY1050 and the corresponding local station.  Local stations
 PY1050  are stations processed simultaneously in a session regardless of
 PY1050  distance.
 PY1050
 PY1050  Accuracy and standard deviation values are given in cm.
