Notes:
1 The DP system will display the Origin of the A and B axes. This could be any
point on the tanker, the main mast, midway between perpendiculars or one of
the reflectors. In this example it is number 1 reflector.
2 The reflector numbering should be chosen so that they form an anti-clockwise
sequence when seen by CyScan.
This can be 1-2-3, or 2-3-1 or 3-1-2, etc.
3 In Auto Survey, target 1 would be the datum (primary target) and denotes the
origin of A/B frame.
