Vela (XYZ)

Notes: This refers to the whole Vela XYZ complex, of which X has at times been classified as a separate (filled-centre) remnant. This remnant is overlapped by G260.4−3.4 and G266.2−1.2.

Radio: Large shell, with flatter spectrum component (Vela X), and pulsar nebula.
Optical: Filaments.
X-ray: Patchy shell, with extensions, central nebula and pulsar.
Point sources: Pulsar within Vela X, with one-sided `jet'.
Distance: Vela pulsar parallax gives 0.3 kpc, optical spectra and HI studies suggest 0.25 kpc.
