XRT digest

Listed below are links to documents relevant to the Swift XRT data analysis and calibration:

Document	Description
XRT data analysis guide	Contains descriptions on how to reduce the XRT data starting from the unfiltered event to the extraction of the spectra lightcurves and images. It also includes a list of major XRT changes in how the instrument operates.
On the Energy scale	Describes the effects contributing to the energy scale offset (spectral analysis)
On the latest ARF and RMF	Describes the latest Response and Ancillary respose function (spectral analysis)
On the latest Gain and CTI	Describes the latest derived Gain and CTI calibration
On the latest Bad pixel	Lists the latest bad pixels
On the position accuracy	Describes the calibration results that defines the new XRT boresight position. See also Moretti et al. astroph/0511604
On the position error	Describes the calibration results that defines the XRT position error.
On the Point spread function	Describes the in-flight calibration of the Swift XRT Point Spread Function
On the effective area	Describes the in-flight on-axis and off-axis effective area measuraments of the Swift XRT
On the spectroscopic performance	Describes the in-flight spectroscopic performace of the Swift XRT CCD camera
Timing accuracy	Describes the in-flight calibration on absolute timing with the Swift xrt
