Interstellar Ca I absorption

We present high-resolution (FWHM~0.3-1.5km/s) spectra, obtained with the AAT UHRF, the McDonald Observatory 2.7m coude spectrograph, and/or the KPNO coude feed, of interstellar...本研究提供了半高全宽~0.3-1.5km/s的高分辨率星际光谱，相关数据分别由英澳望远镜超高分辨率摄谱仪（AAT UHRF）、麦克唐纳天文台2.7米折轴摄谱仪以及/或基特峰国家天文台折轴馈源装置获取。
