'Determination of the longitude of Valentia in Ireland by transmission of chronometers. Forming the appendix to the Greenwich Astronomical Observations, 1845', by G.B. Airy, printed 1846.
The determination of the longitude of Valencia in Ireland by G.B. Airy.
Comparison of chronometers in order to find the longitude of Kingstown (Dún Laoghaire), Ireland, and the difference in longitude between Kingstown and Valentia (Valencia). The chronometers used are 2300, 2388, 2354, 1839 and 'Southampton'.
Observations of stars at Kingstown (Dún Laoghaire), Ireland, in conjunction with chronometer readings to find the longitude of Valentia (Valencia). There are also journals of the project by R. Sheepshanks and J.R. Hind, star catalogues for Kingstown, intervals of transit wires and corrections for collimation of the transit telescope. The chronometers used are numbers 1839, 2354 and 2388.
Observations of stars at Valentia (Valencia), Ireland, in conjunction with chronometers to ascertain the longitude of Valentia. There are also journals of the project, transits observed at Valentia, intervals of transit wires, adjustments to the transit, clock errors, comparison of 'Southampton' and 2306, and the final longitude of Valentia.
Ratings of the chronometers used for determining the longitude of Valentia (Valencia), Ireland, including a large number of references to different chronometers.
Geodetic equations based on the 'Longitude of Valentia' (Valencia) project. The papers include personal equations and geodetic formulae; a diagram of the triangulation employed; angles of places from Butser Hill, Hampshire, and other locations; abstract of latitudes, longitudes and azimuthal bearings; schemes and instructions for the reductions of the observations; and an account of the whole project in draft form by Airy, missing several pages.
Five personal notebooks of geodetic equations as performed on the 'Longitude of Valentia' (Valencia) project, written mainly in pencil.
Airy's printed papers, volume 8, with a list of titles numbered 249-281. The papers are dated from 9 February 1861 ('On the Temperature Correction of Syphon Barometers') to 2 March 1863 ('Determination of the Longitude of Valencia').
