Notes.

(a)

Observation ID for XMM-Newton (X), Chandra (C) and Swift (S).

(b)

Tobs : start day of observation.

(c)

TZero : reference time for calculated PZero and using millisecond accuracy.

(d)

Pulse period derived using the accelerated epoch folding algorithm.

(e)

Spin-up of the pulsar. Data sets with low statistics are marked with star (*), for those a unique solution could not be established and therefore the given uncertainty denotes the characteristic spread between multiple solutions.

(f)

Pulsed fraction (PF = (Fmax − Fmin)/(Fmax + Fmin)) derived form the folded pulse profile using 10 phase bins, we treated uncertainties in phase bins with low numbers of counts by following Gehrels (1986).

(g)

Absorption corrected X-ray Flux (0.3–10.0 keV) of the hard component as derived from the distributions of the marginalised parameters using the Bayesian framework described in the text. Given value denotes the median of the distribution, while error values the 5% and 95% percentiles.

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.
