Which consequence results when an astrolabe's alidade is severely warped?

💡 Explanation

An off-axis alidade causes inaccurate angle measurements because parallax error skews the altitude reading; therefore, stellar positional calculations are severely impacted rather than the projection since the plates remain intact relative to the base.
