Swift-XRT products for GRB 150402A — Source 5

RA/Dec (J2000) = 11h 33m 49.30s, +40° 52′ 39.8″ +/- 4.2 (radius, 90%)

Back to list of objects in this field.

This is the probable afterglow because:

The source is fading at the 3-σ confidence level.

Light curve	Spectrum

We expect ~4.89×10^-3 serendipitous objects at least as bright as this source in this tiled dataset, based on the logN-logS distribution of Mateos et al. (2008) [More details]
