PROBING THE LOCAL BUBBLE WITH DIFFUSE INTERSTELLAR BANDS. III. THE NORTHERN HEMISPHERE DATA AND CATALOG

We present new high signal-to-noise ratio (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 the [lambda]5780 and [lambda]5797 [Angstrom] DIBs up to a distance of ~200 pc. All of the observations were carried out using the Intermediate Dispersion Spectrograph on the 2.5 m Isaac Newton Telescope, during three years, to reach a minimum S/N of ~2000. All of the [lambda]5780 and [lambda]5797 absorptions are presented in this paper and we tabulate the observed values of the interstellar parameters, [lambda]5780, [lambda]5797, Na ID sub(1), and Na ID sub(2), including the uncertainties.
