Calculation of physical parameters from thresholded GAN-generated magnetic patches. The top row shows a GAN-generated AR, its thresholded version, and the derived regions of polarity inversion with a high field gradient from left to right. The collage starting from the second row shows the thresholded version of all GAN-generated images in Figure 2 with field-strength-weighted centroids of positive and negative polarity connected by cyan lines.
