Overview maps of the observed area. Top row, left to right: the intensity of the Ca ii H pseudo-continuum in the far blue wing, the outer and inner wing intensities, and the line-core intensity (H₃). Middle row: the intensity of the Ca ii IR continuum, the monochromatic intensity at −10 and +5 pm from the line core, and the line-core intensity. Bottom row: the Si i continuum intensity, the polarization degree from the POLIS Fe i 630 nm data, the Si i line-core intensity, and the He i line-core intensity. The intensity maps are normalized to the nearby continuum intensity of the average quiet Sun. The contour and circle outline a magnetic field strength of 700 G and the location of the EB, respectively. The arrow marks the direction of disk center.
