Summary
[edit]DescriptionTablas Alfonsíes - INC.1612 - P059.png |
Español: Traducción desde las Tablas Alfonsíes, Incunable 1612, obra de Juan de Sajonia (astrónomo) y publicado por Erhard Ratdolt en 1483. Agregüé unas columnas en el actual sistema decimal correspondiente al sistema sexagesimal ptolemaico.
Corrección: las celdas en fondo verde claro, son datos corregidos a partir de un cálculo propio dado que el documento esta ilegible o dañado. Para tal corrección tomé la primer diferencia, en el sistema decimal, entre las dos primeras filas de cada subtabla y la resté sucesivamente en las filas siguientes conviertiéndolas nuevamente en el sistema sexagesimal. 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. |
