Abstract:
This paper presents an atlas of diffuse interstellar bands together
with tables with measurements of their parameters: central
wavelengths, full widths at half-maximum and equivalent widths. For
this goal the spectra of ten reddened, early-type stars have been
selected. The spectra are of high resolution, ∼100000, and
reasonable signal-to-noise ratio, S/N>300; they cover a wide
spectral range 3500-10000Å and show a lack of evident Doppler
splitting in the interstellar KI line. The measurement technique has
allowed a homogeneous set of data to be achieved. As a result, the
identity of 336 DIBs from previous surveys has been confirmed and 21
new bands have been found.
Description:
This paper is based on the extensive sets of data from three
observatories: European Southern Observatory (ESO)-La Silla,
ESO-Paranal and Terskol (Russia). It involves spectra obtained
during many observing runs between 1996 and 2009 using three
Coude echelle spectrometers: the High Accuracy Radial velocity
Planetary Search (HARPS, programme IDs 60.A-9036(A) and
078.C-0403(A)), the Ultraviolet and Visual Echelle Spectrograph (UVES,
programme ID 082.C-0566(A)) plus data taken from the ESO Science
Archive Facility (programme IDs 67.C-0281(A), 67.D-0439(A),
266.D-5655(A)) and Matrix Echelle Spectrograph (MAESTRO).
