Which outcome arises when lead contamination affects the crafting process of an astrolabe's sighting vanes?

💡 Explanation

When lead contaminates the brass during casting or working, the ductile properties of the vane deteriorate influencing the precise alignment impacting accurate measurements, because the sight pin cannot be aligned properly. Therefore inaccurate celestial altitude values result, rather than corrosion or weak alidade, resulting from fundamentally weaker materials and distorted coordinates from mismatched latitude specific plates.
