Probing the Local Bubble with Diffuse Interstellar Bands. III. The Northern hemisphere data and catalog

preprint2014arXivOpen access

Abstract

We present a new high signal-to-noise (S/N) observations of the Diffuse Interstellar Bands (DIBs) in the Local Bubble and its surroundings. We observed 432 sightlines and obtain the equivalent widths of λλ5780 and λλ5797 Å DIBs up to distance of ∼\sim 200 pc. All observations have been carried out by using Intermediate Dispersion Spectrograph (IDS) on 2.5 m Isaac Newton Telescope, during three years, to reach a minimum S/N ratio of ∼\sim 2000. All λλ5780 and λλ5797 absorptions are presented in this paper and the observed values of interstellar parameter; λλ5780, λλ5797, Na I D lines including the uncertainties are tabulated.
