Left panel: grayscale representation of the inner structure of the NET image of NGC 4848 at full resolution, with contours of the OFF-band image. The white cross marks the center of the molecular hydrogen given by Vollmer et al. (2001), while the white X marks the center of the HI given by Bravo Alfaro et al. (2001). Right panel: high-contrast representation of the Gaussian-smoothed (three-pixel-kernel) NET image to highlight the emission in the tail, with contours of the OFF-band image. The black box marks the region where the flux in the tail was computed.
