Which outcome resulted during medieval Islamic astronomy when astrolabe sighting vanes degraded significantly?

💡 Explanation

When astrolabe sighting vanes degraded, parallax errors increased because accurate alignment with celestial objects became difficult, leading to less precise altitude measurements. Therefore, star position errors increased, rather than improvements in timekeeping or calendar calculations, which depended on other parts of the instrument.
