Left: a 6 cm radio image from the Australia Telescope Compact Array (Gaensler & Wallace 2003), overlaid with the contours of the outer SNR shell and the PWN. Right: A narrowband image of the O IV 25.89 μm line from Spitzer IRS (Ghavamian et al. 2012), overlaid with the radio contours shown on the left. The yellow “X” marks the location of the explosion center (Winkler et al. 2009), and the star indicates the current location of the pulsar, with the arrow pointing in the direction of the pulsar’s motion. The outer contours of the SNR shell and the PWN are approximately 265″ and 130″, respectively. The pulsar is displaced from the center of the PWN to the southeast (the direction of the pulsar’s motion). The distance from the pulsar to the outer edge of the PWN is ∼90″ in the direction of the pulsar’s motion and ∼160″ in the opposite direction toward the northwest.
