The Swift X-Ray Telescope: Status and Performance
David N. Burrows, J. A. Kennea, A. F. Abbey +23
We present science highlights and performance from the Swift X-ray Telescope (XRT), which was launched on November 20, 2004. The XRT covers the 0.2-10 keV band, and spends most of…
Automatic analysis of Swift-XRT data
P. A. Evans, L. G. Tyler, A. P. Beardmore +1
The Swift spacecraft detects and autonomously observes ~100 Gamma Ray Bursts (GRBs) per year, ~96% of which are detected by the X-ray telescope (XRT). GRBs are accompanied by optic…
The in-flight spectroscopic performance of the Swift XRT CCD camera during 2006-2007
O. Godet, A. P. Beardmore, A. F. Abbey +26
The Swift X-ray Telescope focal plane camera is a front-illuminated MOS CCD, providing a spectral response kernel of 135 eV FWHM at 5.9 keV as measured before launch. We describe t…
Accurate early positions for Swift GRBS: enhancing X-ray positions with UVOT astrometry
M. R. Goad, L. G. Tyler, A. P. Beardmore +15
Here we describe an autonomous way of producing more accurate prompt XRT positions for Swift-detected GRBs and their afterglows, based on UVOT astrometry and a detailed mapping bet…
An online repository of Swift/XRT light curves of GRBs
P. A. Evans, A. P. Beardmore, K. L. Page +12
Context. Swift data are revolutionising our understanding of Gamma Ray Bursts. Since bursts fade rapidly, it is desirable to create and disseminate accurate light curves rapidly. A…
