 PY0830  ACCURACIES  -  Complete network and local accuracy information.
 PY0830  CBN         -  This is a Cooperative Base Network Control Station.
 PY0830  DESIGNATION -  FLAGG
 PY0830  PID         -  PY0830
 PY0830
 PY0830  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 PY0830  at the 95% confidence level per Federal Geographic Data Committee
 PY0830  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 PY0830  the standard deviations (one sigma) of the coordinates (NETWORK) or
 PY0830  of the difference in the coordinates (LOCAL) in latitude, longitude
 PY0830  and ellipsoid height.  CorrNE is the (unitless) correlation
 PY0830  coefficient between the latitude and longitude components of either
 PY0830  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 PY0830  the three-dimensional straight-line slope distance, in km, between
 PY0830  station PY0830 and the corresponding local station.  Local stations
 PY0830  are stations processed simultaneously in a session regardless of
 PY0830  distance.
 PY0830
 PY0830  Accuracy and standard deviation values are given in cm.
