Consider the following statements about Sawai Jai Singh's astronomical work : 1. He learnt of the accuracy of European observations, and obtained de La Hire's tables from which he reproduced a refraction table. 2. His astronomers also developed a telescope of their own to observe the lunar phases of Venus. Which of the statements given above is/are correct?

Sawai Jai Singh II of Jaipur, who built the Jantar Mantar observatories, was deeply engaged with European astronomy. He obtained Philippe de La Hire's astronomical tables (Tabulae Astronomicae, 1702) and used them to prepare a refraction table for his own work, the Zij-i-Muhammad Shahi. His astronomers also designed and built their own telescopes, with which they observed the phases of Venus and sunspots. Both statements are therefore correct.
