Alphonsine Tables - Table of the equations of the movement of the access and recede from de 8° sphere

Summary

Description
Español: Traducción desde las tablas del año 1492 (Tablas de Alfonso), obra de Johanni Lucilio Santritter. Agregüé unas columnas en el actual sistema decimal correspondiente al sistema sexagesimal ptolemaico.

El cálculo del valor de la trepidación (movimiento de acceso y receso) requiere de dos tablas. La primera (Tablas Alfonsíes - MSS.7856 - P09b) es una tabla del movimiento de "la Cabeza de Aries" (fija en coordenadas sidéreas), cuya representación es la misma que la de las demás tablas de movimientos medios, y la segunda (presente) es una tabla de la ecuación de "accesso y receso", cuyo argumento se deduce de la primera tabla. No se especifica parámetro alguno, pero se indica que los valores de la segunda tabla (ésta) son positivos desde 0° hasta 180° (acceso) y negativos desde 180° hasta 360° (receso). NdT: párrafo del libro "Las Tablas Alfonsíes de Toledo". Bernard R. Goldstein y José Chabás. Diputación Provincial de Toledo (2008). Pág. 260.

Corrección: las celdas en fondo celeste, son datos corregidos tomados del Incunable 1612, publicado por Erhard Ratdolt en 1483.

La era alfonsí se inicia el Domingo 01.01.1252 a las 12:00 h (mediodía).
