Line-of-sight
error (Hz-
collimation)
The line-of-sight
error is the
deviation from
the perpendicular
between tilting
axis and line-of-
sight. This is
eleminated by
measuring in two
telescope
positions. Zenith
Point on the
plumb line above
the observer.
Standing axis
inclination
Angle between
plumb line and
standing axis.
V-index (Vertical
index error)
With horizontal
line-of-sight the
V-curcle reading
should be exactly
90°(100gon). The
deviation from
this values is
termed V-index
(i). Graticule
Glass plate
within the
telescope with
evaporated
reticle and
distance marks.
Plumb line /
Compensator
Direction of
gravity. The
compensator
defines the
plumb line within
the instrument.
