AA7919 ACCURACIES - Complete network and local accuracy information.
AA7919 CBN - This is a Cooperative Base Network Control Station.
AA7919 DESIGNATION - GREENE 93 2
AA7919 PID - AA7919
AA7919
AA7919 Horiz and Ellip are the horizontal and ellipsoid height accuracies
AA7919 at the 95% confidence level per Federal Geographic Data Committee
AA7919 Geospatial Positioning Accuracy Standards. SD_N, SD_E and SD_h are
AA7919 the standard deviations (one sigma) of the coordinates (NETWORK) or
AA7919 of the difference in the coordinates (LOCAL) in latitude, longitude
AA7919 and ellipsoid height. CorrNE is the (unitless) correlation
AA7919 coefficient between the latitude and longitude components of either
AA7919 the coordinate (NETWORK) or coordinate difference (LOCAL). Dist is
AA7919 the three-dimensional straight-line slope distance, in km, between
AA7919 station AA7919 and the corresponding local station. Local stations
AA7919 are stations processed simultaneously in a session regardless of
AA7919 distance.

AA7919 Accuracy and standard deviation values are given in cm.
