8.3.4 Column Offset Measurement

If it is possible to measure the circumscription point (P1) of a column, the
distance to the center of the column (P0), coordinate and direction angle can be
calculated by observing circumscription points (P2) and (P3).
The direction angle of the center of the column is the average of the observed
angles of circumscription points (P2) and (P3).
