Commentaries include: Ṭūsī’s al-Tadhkira fī `ilm al-hay’a [note Ch. 11 translated into Sanskrit; see this work for an example of a commentary tradition], Taḥrīr al-Majisṭī, and book on astrolabes. In the preface to the last book Birjandī mentions some tables of the positions of stars that he calculated for the year 853 Yazdigird (1484). Birjandī also wrote a commentary on Kāshī’s Zīj-i Khāqānī (Kāshī’s attempt to correct Ṭūsī’s Īlkhānī Zīj);  a commentary on the Zīj of Ulugh Beg (the last date provided in it being 929 H = 1523),  a supercommentary (ḥāshiya) on Qāḍīzāde’s commentary (sharḥ) to Jaghmīnī’s al-Mulakhkhaṣ fī `ilm al-hay’a al-basīṭa. In addition to these commentaries, Birjandī  also wrote several independent astronomical works, whose subjects included cosmology, ephemeredes, instruments of observation, as well as a treatise on the distances and sizes of the planets that was dedicated to Ḥabīb Allāh, and another work on the construction of almanacs completed in 1478/1479.
