<Charles Rundle Davidson> coauthored the original report of the 1919 <Eddington experiment>, with <Frank Watson Dyson> and <Arthur Eddington>. His contribution belongs to an observational project that compared stellar images taken during a total <solar eclipse> with reference images.
Comparing stellar <positions> on eclipse and reference plates tested a small radial displacement. Changes in plate scale and focus could alter the signal, so the report assessed instrumental errors alongside its gravitational interpretation.<A determination of the deflection of light by the Sun's gravitational field by Frank Watson Dyson and others>[1919 observations and 1920 report: observing arrangements, plate comparisons and inferred solar-limb deflection]{ref}
