Table 1:
Overview of the nine most frequent burster sources in the
Galactic center region. They are ordered in decreasing number of
bursts observed per source with the WFC. For each source a factor
(conv.) in erg/count is derived to convert photon flux to energy flux
in 2-28 keV . We also show the net exposure for each individual source
and the distance as quoted in the literature. For each distance
estimate we assume an error of 30%. The distances are derived from:
