Summary
[edit]DescriptionTablas Alfonsíes - Lignères (1322) - P106.png |
Español: Traducción desde las tablas del año 1322 (Tablas de Alfonso), obra de Juan de Lignères. Agregüé una columna en el actual sistema decimal correspondiente al sistema sexagesimal ptolemaico. Esta tabla sólo se aplica cuando el Sol y la Luna están cerca de la sizigia verdadera. La longitud entre las dos luminarias se muestra en intervalos de a 1° de 1° a 7°. Las entradas van de 0;0,0° a 0;0,6° y se deben sumar o restar a la superatio, es decir, la diferencia entre las velocidades horarias lunar y solar. Para una explicación de su uso, véase Chabás y Goldstein 1992, págs. 269-270, y el capítulo 22 de los cánones de las Tablas Alfonsinas parisinas, manuscrito 7856, obra de Juan de Sajonia (astrónomo) (Poulle 1984, págs. 80-87). Esta es la tabla más pequeña del conjunto de Juan de Lignères, con sólo 28 números sexagesimales, incluidos los del argumento. Paralelamente, la tabla se encuentra entre las del Almanaque de Azarquiel (Millás 1943-1950, p. 233) y las Tablas Toledanas (Pedersen 2002, p. 1414). Difiere ligeramente del zij de al-Battānī (Nallino 1899–1907, 2: 88), donde las entradas varían de 0;0,1° a 0;0,7°. No se menciona en los cánones de Juan de Lignères. |
