Notes. N: no time jump, S: time jump corrected by the SAS, E: time jump not corrected by the SAS, data had to be partly excluded from the analysis. TI: timing mode, B: burst mode, M: medium filter, T: thick filter. Epoch: the epoch of the 1st XMM-Newton event. Radio period: the radio period extrapolated to the XMM-Newton epoch. The accuracy of the radio periods can be considered to be good to 10-13, which is almost negligible compared to the X-ray errors of the period.
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.
