Bi-dimensional representation of the Ca ii  H contrast as a function of photospheric magnetic field strength and inclination. Each color rectangle in the scatter plot indicates the mean value of the contrast for a given range of field strengths and inclinations. The white areas are the locations where a particular combination of inclination and field strength is not present in our data.
