Final morphological best fit with a double-torus model.

Parameter	Value	Units

Ψ ^a	114.4 ± 2.3 ± 1.1	°
ζ _PSR	32.5 ± 4.0 ± 1.7	°
R	2.1 ± 0.06 ± 0.08	′′
β _shock	0.41 ± 0.06 ± 0.06	–

Notes. The model was convolved with the PSF as described in the text.

^(a)

For all the parameters except the background counts/pixel, the first error denotes the statistical error, and the second the uncertainty on the estimates associated with the unmodelled components in the fit.
