Absorption-corrected luminosities of the extended emission (blue line; the PWN G29.4+0.1) and the point source PS1 (the PSR) in the 0.5–8.0 keV energy band for a distance range between 5.5 and 7.5 kpc. The blue point represents the values for 6.5 kpc. The error bar corresponds to luminosities calculated between 5.5 and 7.5 kpc. The black stars correspond to a population of X-ray PWNe and their powering PSRs, and the dashed lines are upper and lower bounds defined in Kargaltsev & Pavlov (2008).
