Which outcome occurs when a sextant's mirrors misaligned?

💡 Explanation

Celestial fix becomes less repeatable because sextant mirror error introduces systematic angular measuring error through parallax, and this accumulated uncertainty degrades fix quality; therefore, successive measurements scatter widely rather than aligning within tolerances.
