From the Table you have shown, you ...

Using optical fibers in astronomy
Two main uses:
A fibre-fed spectrograph can be much more stable, because the spectrograph can be mounted solidly in a pressure- and temperature-controlled environment, away from the telescope. Being ...

If you are at zenith, it doesn't matter - the light coming through the atmosphere is not differentially refracted.
If you are away from zenith, then the position of the star in the sky depends on ...
