Comparison between the Stokes V profile (solid) and the derivative of Stokes I with respect to the wavelength. The Stokes profiles are normalised to the quiet-Sun averaged continuum intensity, and the representation of Stokes V is in percentage units. At the same time, we scale the derivative with an arbitrary factor to match the Stokes V amplitude. The location of this pixel is highlighted in colour in Figure 9.
