Fig. 3From: Modeling geomagnetic spikes: the Levantine Iron Age anomalyOptimal parameters of \({B}_{r}^{\mathrm{spike}}\) for the age period considered in this study, from 1150 to 400 BC. The optimal parameters are calculated for each temporal window of 100 years moving every 50 years. The error bars indicate the uncertainty of the optimal parameters at 1σ of significanceBack to article page
