摘要: The high resolution spectrograph on HST, with resolving powers up to 94000 or 3.2 km s−1, is giving us a new look at interstellar absorption lines in the range 1090 3350 A. signal-to-noise ratios possible digicon detectors provide precise line profiles suitable for studying individual velocity components.
