GRB 241113B: Swift-XRT observations

Swift-XRT has performed follow-up observations of the SVOM/ECLAIRs-detected burst GRB 241113B, collecting 1.5 ks of Photon Counting (PC) mode data between T0+10.3 ks and T0+16.1 ks. No X-ray sources have been detected consistent with being within 572 arcsec of the SVOM/ECLAIRs position. The 3-sigma upper limit in the field ranges from ~0.006 to ~0.007 ct s^-1, corresponding to a 0.3-10 keV observed flux of 2.4e-13 to 2.8e-13 erg cm^-2 s^-1 (assuming a typical GRB spectrum). The results of the XRT-team automatic analysis of the XRT observations, including a position-specific upper limit calculator, are available at https://www.swift.ac.uk/ToO_GRBs/00021731.
