An instrument was set up over TBM 1, and backsights onto point A before sighting onto B. The instrument was then moved to B, back-sighted onto TBM 1 and then sighted at C. It was moved once again, to C, back-sighted onto B before being sighted onto D. The line between TBM 1 to point A is to act as the reference plane for the site (taken as zero degrees: 0° 0' 0").
