Qāḍī Zāda al-Rūmī (1364 in Bursa, Ottoman Empire – 1436 in Samarqand, Timurid Empire),
whose actual name was Salah al-Din Musa Pasha (qāḍī zāda means "son of the
judge", al-rūmī "the Roman" indicating he came from Asia Minor,
which was once Roman), was a Turkish astronomer and mathematician who
worked at the observatory in Samarkand. He computed sin 1° to an accuracy of
10−12.
Together with Ulugh Beg, al-Kāshī
and a few other astronomers, Qāḍī Zāda produced the Zij-i-Sultani, the first
comprehensive stellar catalogue since the Maragheh observatory's Zij-i Ilkhani
two centuries earlier. The Zij-i Sultani contained the positions of 992 stars.
