Which purpose benefitted from Islamic scholars improving Ptolemaic models for planetary motion?

💡 Explanation

Improved models refined epicycle calculations reducing errors; this enhanced calendar accuracy because the refined motion models updated predicted positions more accurately. Therefore calendars improved, rather than eclipse forecasting, parallax measurements or confirmation of existing theories.
