K.L. Page (U. Leicester), A.P. Beardmore (U. Leicester), C. Salvaggio
(INAF-OAB), M. Ferro (INAF-OAB), R. Brivio (INAF-OAB), S. Dichiara
(PSU), J.A. Kennea (PSU), D.N. Burrows (PSU) and P.A. Evans (U.
Leicester) reports on behalf of the Swift-XRT team:
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.
