The first basis vector of the frame, l, is in direction of a priori baseline, (r_2 - r_1). Direction of the second vector, h, is defined by a cross product of a priori baseline vector and a priori geocentric vector of the 2nd station. The last basis vector, v, is perpendicular to the vectors l and h and is radially inward at the center of the baseline. For the short baselines, the vectors l and h are close to the horizontal plane and v is almost vertical (with opposite sign). In the table above the columns are: * Vector mag: length of the a posteriori baseline; * Length: l-component of the baseline; * Horizontal: h-component of the baseline; * Vertical: v-component of the baseline; * c-sigma: calculated (using standard deviations of adjusted station coordinates of baselines) standard deviations of the corresponding values.
