 PY0951  ACCURACIES  -  Complete network and local accuracy information.
 PY0951  CBN         -  This is a Cooperative Base Network Control Station.
 PY0951  DESIGNATION -  HULL
 PY0951  PID         -  PY0951
 PY0951
 PY0951  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 PY0951  at the 95% confidence level per Federal Geographic Data Committee
 PY0951  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 PY0951  the standard deviations (one sigma) of the coordinates (NETWORK) or
 PY0951  of the difference in the coordinates (LOCAL) in latitude, longitude
 PY0951  and ellipsoid height.  CorrNE is the (unitless) correlation
 PY0951  coefficient between the latitude and longitude components of either
 PY0951  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 PY0951  the three-dimensional straight-line slope distance, in km, between
 PY0951  station PY0951 and the corresponding local station.  Local stations
 PY0951  are stations processed simultaneously in a session regardless of
 PY0951  distance.
 PY0951
 PY0951  Accuracy and standard deviation values are given in cm.
