Which method refined astronomical calculations through algebraic modeling using Ptolemaic data by medieval Islamic astronomers?

💡 Explanation

When refining Ptolemaic models, Islamic astronomers introduced algebraic adjustments to eccentricities of epicycles because this could be derived using observed planetary positions, thus improving predictive accuracy. Therefore, epicycle eccentricity adjustments happened, rather than alternative adjustments requiring direct physical measurements or observations focused on mapping.
