Notes.

(a)

Most probable period with 1σ error.

(b)

X-ray flux and luminosity in the 0.2–10 keV band.

(c)

Absorption-corrected luminosity assuming a distance of 50 kpc.

(d)

To model the spectra of RX J0501.6–7034 an additional black-body component was included. It contributes 36.7% to the total flux and 35.3% to the luminosity. The for the fit without the black-body component was 1.10 for 731 degrees of freedom (d.o.f.). The F-test probability of 3.2 × 10−16 justifies the addition of this component.
