Overview of the observation in Ca II 8542 Å, Fe I 6302 Å and Ca II K. Top row: from the left Stokes I at Δλ = 85 mÅ and V/I at Δλ = 170 mÅ from line center. Bottom row: from the left Stokes V/I of Fe I 6302 Å at Δλ = 40 mÅ from line center and Stokes I of Ca II K at Δλ = 470 mÅ. The red box indicates the area used in our study.
