Comparison of the spatially integrated multiwavelength spectra of the J1124-5916 PWN for the compact PWN torus (lower curves) and for the much more extended plerion (upper curves) obtained with different instruments, as notified in the plot. The radio and submillimeter data for the plerion are taken from Gaensler & Wallace (2003) and from the Planck Collaboration (2011), respectively. 1σ X-ray uncertainties for each of the spectrum are indicated by hatched regions and are extended toward the low-frequency range. The torus is not detected in the radio, while the plerion is not identified in the IR.
