Additional Information : Intersection of vertical axis of 5/8 inch
: Whitworth threaded steel stub with horizontal
: plane coinciding with top of mounting plate
: to which steel stub is attached. This
: mounting is on top of the North calibration

: For the latest local ties see the
: Stromlo local tie SINEX file lodged with
: IERS.
