Orientation of the moon by numerical integration
--The physical libration angles of the Moon and their time rates at an arbitrary initial epoch.
--Physical constants featuring the principal moments of ineria of the Moon.
--Parameters associated with the particular observational material being used.
Examples are given of comparison between the proposed method and Eckhardt's 1970 model of the physical librations of the Moon. The merits of the new method are discussed in the light of conventional data sources like Earth-based or satellite-based photography as well as newly available data types like Laser ranging to retroreflectors on the Moon.
