Abstract:
Debris discs are a consequence of the planet formation process and
constitute the fingerprints of planetesimal systems. Their solar
system's counterparts are the asteroid and Edgeworth-Kuiper belts. The
Herschel Open Time Key Programme DUNES (DUst around NEarby Stars)
survey aims at detecting extra-solar analogues to the Edgeworth-Kuiper
belt around solar-type stars, putting in this way the solar system
into context.
We used Herschel/PACS to observe a sample of nearby FGK stars. Data at
100 and 160 micron were obtained, complemented in some cases with
observations at 70 micron, and at 250, 350 and 500 micron using SPIRE.
The paper provides a detailed description of the observational results
of the survey.
Description:
The on-line tabular material contains a complete description of the
DUNES objects, providing absolute parameters of the stars, the
photometry used to build their spectral energy distributions, the
Herschel/PACS fluxes, the photospheric predictions at the PACS
wavelengths, the significance of the potential excesses and additional
information concerning the stars with extended emission, the offsets
of the stellar positions as measured in the optical and in the PACS100
images, the AORs (Astronomical Observation Request number) of the
observations and the on-source integration times.

Note (6): When no values of these two parameters are not given it means
that no measurements/determinations have been found in the literature.
In those cases, for the construction of the model photospheres to fit
the SED, logg values were assigned according to the spectral type and
solar metallicity was assumed.
