Summary
[edit]DescriptionTablas Alfonsíes - MSS.7856 - P25b.png |
Español: Traducción desde las Tablas Alfonsíes, manuscrito 7856, obra de Juan de Sajonia (astrónomo). Agregüé unas columnas en el actual sistema decimal correspondiente al sistema sexagesimal ptolemaico. Corrección: la celda en fondo rosa, es un dato corregido tomado del Incunable 1612 publicado por Erhard Ratdolt en 1483. La celda en fondo celeste en la subtabla de la derecha, es un dato erróneo en el Incunable INC/1612. En cada subtabla el "Argumento de la Ecuación" es la ecuación de la anomalía de Mercurio. 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. |
