Which design constraint limited the accuracy of medieval Islamic astrolabes used in trigonometry?

💡 Explanation

When celestial sphere is projected onto a flat astrolabe face, conformal mapping preserves local angles but introduces distortion dependent on distance from Tangent point due to geometric projection, skewing measurements. Therefore planar projection limits accuracy, rather expansion, axiomatic limits, or subjective errors which would require material flaws, faulty proofs or human interpretations repectively .
