摘要：
The wide range of UV extinction properties in the Small Magellanic Cloud (SMC) probably traces the effects of star formation on interstellar dust. The Swift UVOT, with its three UV filters (centred at 1800, 2200 and 2500 A respectively) and three optical filters, is an ideal instrument to map this extinction. We present preliminary results of six-band photometry in a similar to 3.3' square field in the SMC. Fitting the resulting optical/UV spectral distributions with a dust model, we estimate the depths of extinction for 53 stars and use this to map the distribution of dust in the observed field. We briefly discuss the relevance of this study for star forming galaxies, including the hosts of Gamma-Ray Bursts.
