Intensity contrast of solar plage as a function of magnetic flux at high spatial resolution

F. Kahil, T. L. Riethmüller, S. K. Solanki

Magnetic elements have an intensity contrast that depends on the type of region they are located in (e.g. quiet Sun, or active region plage). Observed values also depend on the spa…
