TL;DR: In this article, the photometric calibration of the Swift Ultraviolet/Optical Telescope (UVOT) was performed with observations of standard stars and standard star fields that represent a wide range of spectral star types.

TL;DR: In this paper, the photometric calibration of the UV/Optical Telescope (UVOT) has been described, and details on other aspects of the calibration including a measurement of the point spread function with an assessment of the orbital variation and the effect on photometry.

TL;DR: The relationship between the LAT-detected GRBs and the well-studied, fainter, and less energetic GRBs detected by the Swift Burst Alert Telescope is only beginning to be explored by multi-wavelength studies as discussed by the authors.

TL;DR: In this article, the authors report the results of the Swift and XMM-Newton observations of the discovered GRB 060729 (T90 = 115 s) and show that the afterglow of this burst was exceptionally bright in X-rays as well as at UV/optical wavelengths, showing an unusually long slow decay phase (? = 0.14? 0.02), suggesting a larger energy injection phase at early times than in other bursts.
