Contribution
It presents a comprehensive catalog of DIB equivalent widths and interstellar parameters for 432 sightlines in the northern hemisphere, expanding the dataset of local interstellar medium observations.
Findings
Detected DIBs in all observed sightlines.
Provided detailed interstellar parameter measurements.
Enhanced understanding of local interstellar medium structure.
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 5780 and 5797 \AA\ DIBs up to distance of 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 2000. All 5780 and 5797 absorptions are presented in this paper and the observed values of interstellar parameter; 5780, 5797, Na I D lines including the uncertainties are tabulated.
