Abstract
The Ultraviolet and Optical telescope (UVOT) on board the SWIFT observatory, plays an important part in the quest to understand gamma-ray bursts. As its name suggests, the UVOT obtains ultraviolet and optical data at high time resolution, with 7 broad band filters and 2 low resolution grisms. This paper forms the second of a pair of papers presenting the initial on-board calibration of the UVOT. The first one (Part 1) deals with distortion, large and small scale sensitivity variations and the telescope point spread function. In this paper we cover the following topics: the photometry of the broadband filters including colour transformations and linearity; the wavelength calibration and sensitivities of the grisms; time resolution and red leak.
