a Spectral
parameters not used in the model for a particular object are marked
as ``-''.
b F-test probability that the fit improvement achieved by the inclusion of a hard tail in addition to a cutoff powerlaw was by chance, i.e. that the hard tail is not real. Note that since ISGRI has lower sensitivity above 500 keV and none above 700 keV, we can in most cases not test for the presence of the additional component but only check the compatibility with the ISGRI data.
c Parameters of alternative fit models are given in Sect. 4.
d Spectrum very probably flawed by source contamination from IGR J16358-472.

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.
