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 λ5780 and λ5797Å DIBs up to a distance
of ∼200pc. All of the observations were carried out using the
Intermediate Dispersion Spectrograph on the 2.5m Isaac Newton
Telescope, during three years, to reach a minimum S/N of ∼2000. All of
the λ5780 and λ5797 absorptions are presented in this
paper and we tabulate the observed values of the interstellar
parameters, λ5780, λ5797, Na ID1, and Na ID2,
including the uncertainties.
Description:
All of the observations have been obtained with the Intermediate
Dispersion Spectrograph (IDS) at the 2.5m Isaac Newton Telescope at
the Roque de Los Muchachos in La Palma; with spectra in the
5750-6040Å region at spectral resolutions of R∼2000 (or a velocity
resolution of Δv=150km/s).
