TL;DR: The Swift Gamma-Ray Explorer (XRT) as mentioned in this paper uses a mirror set built for JET-X and an XMM-Newton/EPIC MOS CCD detector to provide a sensitive broad-band (0.2-10 keV) X-ray imager with effective area of > 120 cm2 at 1.5 keV, field of view of 23.6 × 23. 6 arcminutes, and angular resolution of 18 arcseconds.

TL;DR: The Swift Gamma-Ray Burst Explorer (XRT) as mentioned in this paper is designed to make prompt multiwavelength observations of Gamma-ray Bursts (GRBs) and their afterglows, and provides key capabilities that permit Swift to determine GRB positions with several arcsecond accuracy within 100 seconds of the burst onset.

TL;DR: Moretti et al. as discussed by the authors measured the PSF of the SWIFTX-RTPoint Spread Function (PSF) as measured during the end-to-end calibration campaign at the Panter X-Ray b eam line facility.
