Which consequence arose from imperfect alignment during installation of large medieval Islamic astronomical instruments?

💡 Explanation

When astronomical instruments such as quadrants were not installed perfectly, parallax error resulted because their alignment with the intended celestial meridian was off. This impacted accuracy, therefore positional errors occurred, rather than structural failures or environmental effects.
