TITLE: GCN CIRCULAR NUMBER: 9609 SUBJECT: XRF 090702: Swift-XRT refined analysis DATE: 09/07/03 18:26:52 GMT FROM: Boris Sbarufatti at INAF-IASF-Pa Sbarufatti B., Mangano V. (INAF-IASFPA) report on behalf of the Swift Team: We have analyzed the Swift-XRT data of XRF 090702 (Paizis, et al., GCN Circ. 9603) comprising 6 ks in Photon Counting (PC) mode from T+16.5 ks to T+25.4 ks. The best position for the X-ray afterglow is the XRT UVOT-enhanced position: RA, Dec = 175.89704, +11.50161 which is equivalent to: RA (J2000): 11h 43m 35.29s Dec (J2000): +11d 30' 05.8" with an uncertainty of 5.0 arcsec (radius, 90% confidence). The light-curve consists of two data points at the level of some 1E-3 counts/s, and shows evidence of a fading behaviour. A power-law extrapolation of the available data indicates a count-rate of 9.4E-5 counts/s at T+48 h. The average spectrum was fitted using Cash statistics with an absorbed power-law model. The absorbing column NH was fixed at the Galactic value of 3.5E20 cm^-2, the photon index is 1.9+/-0.4. The observed (unabsorbed) flux is 2.8(3.0)E-13 ergs cm^-2 s^-1. The C-statistic is 29.3 with 32 bins. The count-rate to flux conversion factor is 4.4E-11. All quoted errors are at 90% confidence level.
