Swift-XRT products for GRB 160521B — Source 1

RA/Dec (J2000) = 09h 50m 39.96s, +79° 01′ 49.7″ +/- 4.2 (radius, 90%)

Back to list of objects in this field.

Source 1 has been manually confirmed as the GRB afterglow so these products are no longer updated. The up-to-date data for the afterglow are now available through the main GRB results area for this GRB.

This is the probable afterglow because:

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

Light curve	Spectrum

We expect ~1.82×10^-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]
