Haro 14 maps in emission lines: Top-left: Hα emission line flux map of Haro 14; the chain-like structure and the curvilinear feature in the central regions are indicated with white lines. The blue line (bottom-left) corresponds to 1 kpc. Top-right: Hα emission line flux map with the intensity in the inner galaxy regions saturated in order to enhance the faint surface brightness features in the outer galaxy parts; the white lines indicate the most prominent shells and filaments in the galaxy periphery. Bottom-left: Hα equivalent width map (in Å); the blue line roughly delineates the bluish regions of the galaxy at intermediate intensity levels. Bottom-right: [O III] λ5007 flux map. Flux units in the emission line maps are 10⁻²⁰ erg s⁻¹ cm⁻² (per spaxel); the central white cross marks the position of the galaxy peak in continuum.
