| Title | Davidson, Charles Rundle: certificate of election to the Royal Society |
| Citation | Distinguished as an Astronomer and Astrophysicist. Has taken an important share in the following investigations which have been largely entrusted to him: - (1) Determination of the Solar Parallax from observations of Eros (1900). (2) Photographic Magnitude of Stars to 9.0 in the Greenwich Section of the Astrographic Chart. (3) Effective wave-lengths of stars from 80 degrees to the North Pole. (4) Determination of Stellar Parallax. (5) Spectro-photometric determination of the Colour Temperatures of Stars. Important photographic and spectroscopic work in many eclipse expeditions, particularly in 1919 when the bending of light by the sun's gravitational field was verified, and in 1926 when the chromospheric spectrum was extended by him nearly to the limit imposed by atmospheric absorption. |
