Which function did the 'rete' accomplish within early Islamic astrolabes?

💡 Explanation

The rete simulated the celestial sphere by employing stereographic projection, because this allowed a 2D model to track many stars; therefore, it mapped stellar positions, rather than directly measuring orbital distances which would require different instruments.
