About these products.

Get another burst.

Add time-sliced spectrum.

The spectral fits assume a redshift: 1.44 (GCN 11089)

Non-standard pipeline processing was used to produce these data. Times when the XRT was hotter than -51.5 degrees were removed; and the object position in the FITS headers was corrected
