Swift-XRT team:
Swift-XRT has performed follow-up observations of the Einstein Probe/WXT-detected
source EP250806a (EP trigger 01709198415, GCN #41246), collecting 1.5 ks of Photon
Counting (PC) mode data between T0+11 ks and T0+13 ks after the trigger. No X-ray
sources have been detected in the WXT error region.
The results of the XRT-team automatic analysis of the XRT observations, including a
position-specific upper limit calculator, are available at
