9.4 Adjustment of Compensation Systematic Error of
Instrument
1) Error of vertical axis (X,Y tilt sensor offset)
2) Collimation error
3) Error of vertical angle 0 datum
4) Error of horizontal axis
The above mentioned errors will be compensated by software, which calculated internally
according to each compensation value.
Also these errors can be compensated by software collimating one side of the telescope that
is carried out to delete the error by turning in normal and reverse both sides of telescope so far.
