Version 1.1.0: Precession added (Hipparcos is epoch J1991.25), sign error in the Z (up) component of v in the (u,v) computation, improved accuracy in the HA <--> UT conversion, and a 0.5 day error in date for Sun's ecliptic coordinates. Thanks to Antoine Merand for helping me locate these bugs. Also new plotting option: Projected Baseline vs. UT. CHARA baseline solution of 2004 9 28 included. (27/Apr/05)
