CK2502 ACCURACIES - Complete network and local accuracy information.

CK2502 Horiz and Ellip are the horizontal and ellipsoid height accuracies
CK2502 at the 95% confidence level per Federal Geographic Data Committee
CK2502 Geospatial Positioning Accuracy Standards. SD_N, SD_E and SD_h are
CK2502 the standard deviations (one sigma) of the coordinates (NETWORK) or
CK2502 of the difference in the coordinates (LOCAL) in latitude, longitude
CK2502 and ellipsoid height. CorrNE is the (unitless) correlation
CK2502 coefficient between the latitude and longitude components of either
CK2502 the coordinate (NETWORK) or coordinate difference (LOCAL). Dist is
CK2502 the three-dimensional straight-line slope distance, in km, between
CK2502 station CK2502 and the corresponding local station. Local stations
CK2502 are stations processed simultaneously in a session regardless of
CK2502 distance.

CK2502 Accuracy and standard deviation values are given in cm.
