Alphonsine Tables - Right Ascencions and Equation of Time. Third table
Summary[edit]
| Description |
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.
La Ecuación del Tiempo está dada por el siguiente cálculo: E = α2 - α1 - (λm2 - λm1), donde α2 y α1 son las ascensiones rectas del Sol para cada longitud verdadera del Sol y λm2 y λm1 las longitudes medias del Sol. Los subíndices 1 y 2 corresponden: el subíndice 1 a datos para el 1° de Enero y el subíndice 2 a datos para cualquier fecha del año. NdT: del libro "Tablas Alfonsíes de Toledo" de José Chabás y Bernard R. Goldstein, pág. 226, Capítulo 29. Las celdas en fondo celeste son mis correciones al Incunable 1612. |
