Plots showing the relations between the total magnitude ﹩m_{\mathrm{total}\,}﹩, the magnitude of the upper nebulae ﹩m_{u}﹩, the magnitude of the lower nebula ﹩m_{l}﹩, the magnitude difference between the left and right sides of the upper nebula ﹩m_{ul}-m_{ur}﹩, and the magnitude difference between the left and right sides of the lower nebula ﹩m_{ll}-m_{lr}﹩. The symbols denote the filter: F555W or F547M (plus signs), F606W, F675W, or F625W (asterisks), and F814W (circles).
