Which mechanism limited the overall accuracy of sundial-astrolabe hybrids despite precise construction materials?

💡 Explanation

When combining sundial and astrolabe functions, the blurring of the sunset/sunrise shadow edge caused by the comparatively large angular size of the solar disc reduces precision for time and angle measurements. Therefore, solar disc size causes inaccuracy rather than albedo, air, or angle manufacturing variations, which pose minor limitations compared to solar disc size.
