Spin frequency evolution folded with a period of 7746 d and centered on most recent measurements. The most recent measurements have been shifted for a better comparison, with the same spin frequency scale. Black empty circles, filled gray squares and filled gray inverted triangles correspond to the most recent Fermi/GBM measurements and BATSE and RXTE/ASM measurements from Wilson et al. (2005), respectively. The vertical dotted line indicates the time of the OPJ95 and of the predicted orbital phase shift.

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.
