Which limitation arises when early astrolabes employed inaccurate 'tympan' plates?

💡 Explanation

Inaccurate tympans induce errors into altitude/azimuth mappings because stereographic projection relies on accurate local horizon representation; therefore the positions calculated are impacted, rather than the structural components or expansion coefficient of the instrument.
