TITLE: GCN CIRCULAR NUMBER: 6785 SUBJECT: GRB 070913: Corrected BAT position DATE: 07/09/13 02:33:41 GMT FROM: Craig Markwardt at NASA/GSFC/UMD C. B. Markwardt (CRESST & NASA/GSFC), S. D. Barthelmy (NASA/GSFC), on behalf of the Swift BAT Team, report: As noted in GCN #6781, currently Swift is calibrating its new gyroscope configuration for the roll axis. In GCN Circ #6782, we quoted an error circle radius of 3 arcminutes for the BAT position for GRB 070913. This radius was incorrect. The correct value was distributed in the Notice (radius ~9.97 arcmin). We apologize for this error and any inconvenience this may have caused. In ground analysis, we have now applied the roll axis correction, and the new best position is, RA, Dec 228.734, -24.290, which is: RA(J2000) = 15h 14m 56s Dec(J2000) = -24d 17' 23" with an uncertainty of 3 arcmin radius, 90% containment, including systematic uncertainty). This is a shift of 6.2 arcmin from the position quoted in GCN Circ #6782.
