If
e = the total pointing error,
e
= the mechanical error,
e
= the error from the 7 parameters of
the pointing model,
e
= the encoder error,
e
= the thermal error,
e
= the tracking error,
e
= the error from noise in the FIVEPOINT measures,
e
= the error of inclinometry data,
e
= the error from the track model,
e
= the seeing,
then
e
= e
+ e
+ e
+
e
+ e
+
e
+ e
+ e
+
e
eqn. (1)
We will return to an analysis of this equation after looking at the current
performance of the track and possible future performance.
