B.-B. Zhang (PSU), Dirk Grupe (PSU). D. Malesani (DARK/NBI) and J. Kennea (PSU)
report on behalf of the Swift-XRT team:
We have analyzed 6.8 ks of XRT data for the INTEGRAL-detected burst:
GRB 130514B, from 314.3 ks to 321.1 ks after the INTERGRAL trigger.
The data are entirely in Photon Counting (PC) mode. We confirm that
the X-ray source reported in Zhang et al. GCN 144651 has been faded with
current count rate of around 3e-3 count/s. The light curve can be modeled with
a power-law decay with a decay index of alpha=0.98 (+0.27, -0.15).
We therefore conclude that the X-ray source reported in Zhang et al. GCN 144651
is the X-ray afterglow of GRB 130514B.
The results of the XRT-team automatic analysis are available at
