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

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 $\lambda$5780 and $\lambda$5797 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 $\lambda$5780 and $\lambda$5797 absorptions are presented in this paper and the observed values of interstellar parameter; $\lambda$5780, $\lambda$5797, Na I D lines including the uncertainties are tabulated.
