appears. Selecting:
Yes returns to the Sight target point screen to take an additional measurement. A maxi-
mum of five target points can be used.
No proceeds to the STN. ORIENTATION RESULT screen.
If more than one target point is measured then the orientation is computed using the "least
squares method".
IF THEN
the orientation is only measured in face II the horizontal direction is based on
face II.
the orientation is measured only in face I or a mixture
of I and II
the horizontal direction is based on
face I.
a target point is measured several times in the same
face
the last valid measurement is used
for the computation.
Field Description
Pts Number of points used in the calculation.
Stn Station name for which the orientation has been set.
