Listed as a separate work in GAS VI.280, no. 10, but it most likely is the Kullīyat al-arṣād, not a separate work, since "Maʿrifat tarkīb al-aflāk" is part of the title of Kullīyat al-arṣād as found in Jūzjānī's intro to the Riyāḍiyyāt supplement to the Najāt.(see Ragep and Ragep, Astron. and Cosm. Works of Ibn Sīnā, p. 7).
