\medskip
$^a$~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.~\ref{secresults}. \\
$^d$~Spectrum very probably flawed by source contamination from  IGR~J16358-472.
