There is a well-known total solar eclipse which occured in Babylon (32° 32′ 31.2″ N, 44° 25′ 12″ E) : 15 April 136 BC or -135.
According to Fred Espenak/NASA, the maximum eclipse time was : 5:27:11 UT and the Sun altitude / azimuth was : 35° / 103°.
When using the default ephemeris of Stellarium (0.14.90.8461, Windows 64 bits), the result is consistent with the calculation of Fred Espenak, however if I use JPL DE431, the maximum eclipse time is : 5:42:00 UT and the Sun altitude / azimuth is 38° / 106°.
Do you intend to solve this problem for the next version 0.15 ?
Anyway thank you for your amazing work improving Stellarium.
