Histograms of Φ found in plages. The three coloured histograms were obtained using core pixels, where red refers to log (τ) = 0, green shows to log (τ) = −0.9 and blue refers to log (τ) = −2.3. The dashed histogram shows Φ of canopy pixels at log (τ) = −2.3. The dotted line represents a homogeneous distribution.
