Which outcome results should an astrolabe not fully align its alidade?

💡 Explanation

Inaccurate celestial inclination readings occur because parallax error introduces angular displacement on non-parallel sighting targets during observation using the Index Mechanism therefore incorrect results, rather than merely damage, arise under this error condition.
