G5.4−1.2 ADS: search fulltext or title/keyword/abstract

Milne 56

• Right Ascension: 18 02 10
• Declination: −24 54
• Size (/arcmin): 35
• Type: C?
• Flux density at 1 GHz (/Jy): 35?
• Spectral Index: 0.2?

Notes: Part been called G5.3−1.0. Has been suggested that this is not a SNR.

Radio: Incomplete shell, including wide `v' of emission to E with small flat-spectrum source at apex.

Optical: Detected.

X-ray: Pulsar detected, with faint extension.

Point sources: Pulsar nearby, in flat spectrum source.

Distance: HI absorption suggests >4.3 kpc, optical extinction suggests 3.9 kpc.
