Evolution of the LOS magnetic flux and the estimated σ for a single generated AR. (a) Evolution of magnetic flux for the generated AR shown in Figs. 6e and f. Solid-red and dashed-blue lines are the positive and negative flux, respectively. The black line shows the seed model magnetic flux. (b) Estimated σ using Eq. (5) applied to the seed model and the generated AR. The red-solid (blue-dashed) line corresponds to σ for the positive (negative) polarity. The black line corresponds to σ estimated with all the pixels within the generated AR field.
