A Comparative Study of Visual and Photoelectric Timing of Occultations

L. V. Morrison
1971 Highlights of Astronomy  
The timing of occultations of stars by the Moon provide data for the following studies:(a)Lunar theory- Constants and secular changes of its orbit.(b)Fundamental star systems- Systematic corrections to equinox and obliquity; individual star corrections.(c)Rotation of Earth- Comparison of atomic and ephemeris time scales.With these applications in mind we consider the analysis of the [O-C]'s from occultations.
