Swift-XRT products for GRB 150902A — Source 4

RA/Dec (J2000) = 14h 20m 41.55s, -69° 27′ 01.7″ +/- 7.8 (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Source 1 has been manually confirmed as the GRB afterglow so these products are no longer updated.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.

Light curve	Spectrum

We expect ~1.89×10^-2 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]
