1 The coordinates listed here are computed with the best available knowledge of the instrumental attitude and with the latest version of the S/W. They supersede the ones reported earlier either through IBAS Alert Packets, GCNs, or refereed papers.
2 The circular error radius (90% c.l.) is computed adding 1 arcmin of systematic error to the statistical one, which is a function of the signal-to-noise ratio.
3 The peak flux is computed over 1 s.
4 Only the references containing INTEGRAL results are reported here.
