Abstract
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 ?5780 and ?5797 Å 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 ?5780 and ?5797 absorptions are presented in this paper and we tabulate the observed values of the interstellar parameters, ?5780, ?5797, Na ID1, and Na ID2, including the uncertainties.
