 KV1921  ACCURACIES  -  Complete network and local accuracy information.
 KV1921  DESIGNATION -  AP STA A PNE
 KV1921  PID         -  KV1921
 KV1921
 KV1921  Horiz and Ellip are the horizontal and ellipsoid height accuracies
 KV1921  at the 95% confidence level per Federal Geographic Data Committee
 KV1921  Geospatial Positioning Accuracy Standards.  SD_N, SD_E and SD_h are
 KV1921  the standard deviations (one sigma) of the coordinates (NETWORK) or
 KV1921  of the difference in the coordinates (LOCAL) in latitude, longitude
 KV1921  and ellipsoid height.  CorrNE is the (unitless) correlation
 KV1921  coefficient between the latitude and longitude components of either
 KV1921  the coordinate (NETWORK) or coordinate difference (LOCAL).  Dist is
 KV1921  the three-dimensional straight-line slope distance, in km, between
 KV1921  station KV1921 and the corresponding local station.  Local stations
 KV1921  are stations processed simultaneously in a session regardless of
 KV1921  distance.
 KV1921
 KV1921  Accuracy and standard deviation values are given in cm.
