Notes. (*) Counts extracted from a 20 pixel radius region. Data were all taken in window timing mode. (#) Pulsed fractions were computed folding the data (20 bin) at the P = 0.467045 s period and fitted with a single sinusoidal function plus constant. Errors are at the 90% confidence level. (+) In these folded light curves there is just one point which drives the fit, resulting in a large pulsed fraction.
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.
