ST correlation versus inclination (upper panel, all latitude configurations for plages and filaments), ST correlation versus plage latitude (middle panel, inclination of 60° only), and difference between filament and plage latitude (lower panel, inclination of 60°), for two longitude configurations: difference in longitude between the plage and the filament of 0° (left panels) and 20° (right panels). Colours from yellow to green correspond to increasing filament latitude in all cases. The different line styles in theupper panel correspond to different plage latitudes.
