Normalised and superimposed model (133 and 207.54 yr cycles) for TSI comparison

Abstract

A normalised and superimposed model, anchored at 1183 BC. The model is based on the interaction between a 133-yr cycle and the perihelion at 207.54-yr intervals. The 133-yr cycle is one of variations in distance (Earth-Sun and Earth-Moon) and solar declination data found in Metonic lunation data (Kelsey, 2018). These variations in distance affect TSI, insolation, and gravitation.
