Properties of the disk center side penumbra (excluding the outermost penumbra) at τc = 0.95. Pixels with opposite polarity field in the solar frame are indicated with red color. Panel a) shows the LOS velocity (clipped at (–4.0, 2.5) km s-1), panel b) the temperature (clipped at (4500, 6500) K), panel c) the vertical magnetic field (in the solar frame; clipped at (–1000, 2200) G), and panel d) the horizontal magnetic field strength (in the solar frame; clipped at 1500 G). The FOV shown is 8 × 15′′. Tick marks are at 1′′ intervals.
