Unidentified SPI-ACS bursts

List of unidentified bursts detected by INTEGRAL/SPI-ACS in April 19-21 and May 5-6, likely associated with activity of magnetar (1E 2259+586 or SGR 1806-20)

Estimates of the flux are lower limits in 100-1000 keV using conversion factor from Vigano and Mereghetti 2009.
The last two coloums show relative position of two magnetars (1E 2259+586 and SGR 1806-20).
