TITLE: GCN CIRCULAR NUMBER: 8010 SUBJECT: GRB 080723B - correction to flux conversion factor DATE: 08/07/24 08:15:47 GMT FROM: Kim Page at U.of Leicester K.L. Page and J.P. Osborne (U. Leicester) report on behalf of the Swift-XRT team: The counts to flux conversion factor in GCN Circ. 8009 was inadvertantly mistyped. The actual conversion is 5.9x10^-11 erg cm^-2 count^-1 (a factor of 100 lower than that previously given). This implies that the predicted flux at 24 hours is 2.4x10^-12 erg cm^-2 s^-1. We apologise for the mistake and any inconvenience it may have caused.
