Notes. All errors stated are the 90% confidence limit unless otherwise stated.

(a)

Normalisation of power law components in units of photons keV−1 cm−2 s−1 at 1 keV.

(b)

Normalisation of Gaussian components in units of total photons cm−2 s−1 in the line.

(c)

Flux values calculated over 0.2–10.0 keV for the XMM-Newton spectra and 2.0–10.0 and 2.0–79.0 keV respectively for the NuSTAR spectra.

(d)

NuSTAR response does not extend below 3 keV where this component dominates in the XMM-Newton spectra and so the normalisation of this component is fixed at zero.

(e)

1σ error; xspec could not compute the 90% confidence limit.

(f)

Normalisation of Blackbody component in units of , where L39 is the luminosity of the Blackbody in units of 1039 ergs s−1 and D10 is the distance to the source in units of 10 kpc.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
