Abstract:We examine new observations of NGC 2808, taken with the far-UV and near-UV cameras on the Space Telescope Imaging Spectrograph (STIS) on board the Hubble Space Telescope (HST). Images were obtained in the far-UV crystal quartz (FUV/F25QTZ; pivot wavelength 1600{AA}), near-UV 2700{AA} continuum (NUV/F25CN270), and clear CCD (CCD/50CCD; pivot wavelength 5850{AA}) modes, employing a cross-shaped dither pattern. ...(more)
