GCN Circular 10414
D. Grupe (PSU) reports on behalf of the Swift-XRT team: We have analyzed 274 s of XRT data for GRB 100213A (Grupe et al. GCN Circ. 10411), from 86 s to 361 s after the BAT trigger. The data are entirely in Photon Counting (PC) mode. At this point only data of the first orbit are available. Further observations have been delayed due to the detection of GRB 100213B (Vetere et al., GCN Circ. 10412). Therefore no prediction of the future light curve is possible at this time. A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 2.04 (+0.45, -0.56) with the absorption column density fixed to the Galactic value of 1.1 x 10^21 cm^-2 (Kalberla et al. 2005). The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 4.5 x 10^-11 (5.9 x 10^-11) erg cm^-2 count^-1. The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00412217. This circular is an official product of the Swift-XRT team.
