Which consequence occurred when early sextant mirrors had imperfections?

💡 Explanation

An imprecise celestial fix arose because index error from imperfect mirror parallelism in the sextant introduced systematic angular errors measuring star altitude. These corrupted angle readings, therefore compromised navigation precision, rather than chronometer accuracy, hull integrity or sail durability.
