Two-dimensional density plots indicate the mutual relationship between estimated spatial and magnetic field parameters for flaring and non-flaring anemone active regions and coronal holes. The top panels a–d show probability densities of area and minimum-distance parameters, while the middle panels e–h highlight the mutual variations in magnetic field and minimum-distance estimates. The bottom panels i–l highlight the relationship between magnetic field and area parameters of anemone AR and CH, with and without flares. Peak magnitudes for corresponding parameters are annotated in each plot.
