FOV of AR 11506 analyzed within this article (corrected for local instrumental wavelength shifts), sampled at four positions within the Hα line scan: the far blue wing (approximately −1.8 Å; top left), the near blue wing (−0.95 Å; top right), the Hα line core (0 Å; bottom left), and the red wing (+0.95 Å; bottom right). The black boxes in each image indicate the regions of interest analyzed in the following sections. A known artifact of the image reconstruction process is visible in the far blue wing at (883, −260).
