Summary

[edit]
Description
Español: Traducción desde las Tablas Alfonsíes, manuscrito 7856, obra de Juan de Sajonia (astrónomo). En esta tabla del movimiento de "la Cabeza de Aries" o movimientos de los apogeos y de las estrellas fijas, "agregüé unas columnas [°/días] en el actual sistema decimal correspondiente al sistema sexagesimal ptolemaico.

También agregüé dos últimas columnas a cada subtabla y la 1° fila de la subtabla de la izquierda, la tomé del manuscrito 7326. Luego, la 2° fila es igual a la anterior (1°) más el incremento de 0,0000201144547325 (0° 0' 0,72") y así sucesivamente para el resto de las 58 filas.
El día sidéreo actual = 24h - 0,06553011111h = 23,93446989h o 23h 56m 4,091604s.
El día sidéreo es el tiempo que se mide entre dos pasos sucesivos (culminación superior) de una misma estrella ecuatorial.

La era alfonsí se inicia el lunes 01.01.1252 a las 12:00 h (mediodía), DJ 2178351 (Día Juliano). Según la Editio Princeps la era alfonsí comienza el sábado 01.06.1252 a las 12:00 h (mediodía), coronación del Rey Alfonso X, luego de 152 días del comienzo según las tablas alfonsíes castellanas.
