Cloud Structure and Physical Conditions in Star-forming Regions from Optical Observations. I. Data and Component Structure
K. Pan, S. R. Federman, K. Cunha +2
We present high-resolution optical spectra (at ~0.6--1.8 km s-1) of interstellar CN, CH, CH^+, \ion{Ca}{1}, \ion{K}{1}, and \ion{Ca}{2} absorption toward 29 lines of sight in three…

High-Resolution Observations of Interstellar Ca I Absorption -- Implications for Depletions and Electron Densities in Diffuse Clouds
Daniel E. Welty, L. M. Hobbs, Donald C. Morton
We present high-resolution (FWHM ~ 0.3-1.5 km/s) spectra of interstellar Ca I absorption toward 30 Galactic stars. Comparisons of the column densities of Ca I, Ca II, K I, and othe…
