Notes.
Fluxes are given in units of 10−12 erg cm−2 s−1 and represent the integrated flux over the range 0.2 to 2 keV. The fluxes are derived from the best-fitting models for each dataset.
Slope of the best-fit single power-law model. The errors on the fit parameters are somewhat unreliable, as this simple model proves to be a poor fit to the spectrum for J234402. For the XMM-Newton observation and the Swift-XRT observation on 18-01-2021 the fits are too poor to estimate an uncertainty, these measurements have been marked with an (*).
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.
