Descrption:
The first version of the Herschel/SPIRE Point Source Catalogue (HSPSC
or SPSC), containing more than 1,6 million entries spread between the
three SPIRE bands, has been released on 7 February 2017.
The catalogue consists of three tables, one for each SPIRE photometric
band.
The SPIRE instrument onboard Herschel mapped about 9% of the sky in
sub-millimeter broad-band filters centred at 250, 350 and 500 microns
(1199, 857, 600GHz, respectively) with spatial resolutions of 17.9",
24.2" and 35.4", respectively. The SPSC was extracted from a total of
6878 Herschel/SPIRE observations, consisting of a serendipitous mix of
programme science observations with sky coverage to various depths and
calibration observations performed in standard configurations.
The SPSC photometry was obtained by a systematic and homogeneous
source extraction procedure, followed by a rigorous quality check that
emphasized reliability over completeness. Regions affected by strong
Galactic emission, mostly in the Galactic Plane, were excluded, as
they pushed the limits of the four source extraction methods that were
used. Aimed primarily at point sources, the SPSC also contains a
significant number of slightly extended sources. Due to the relatively
large spatial extent of the SPIRE beams, a number of point or extended
sources in the SPSC can actually be composites of multiple sources
seen at shorter wavelengths. Users are encouraged to trace back
catalogue entries to the originally contributing detections in SPIRE
observations via the cross identification table available for
download, which provides links between the individual catalogue
entries (SPSCIDs) and the relevant observation identifiers (OBSIDs) in
the Herschel Science Archive.
For further details on catalogue construction, detailed content, and
validation, please see the SPIRE Point Source Catalogue Explanatory
Supplement (supp.pdf). Users should pay particular attention to the
Cautionary Notes in this document before using the contents of the
SPSC for their research.

Note (G1): The object identifier consists of two parts, acronym and sequence,
and is formatted as HSPSCwwwA_Jhhmm.mm+ddmm.m with the exception of the
planets Uranus and Neptune, whichare following the format HSPSCwwwAppp000
HSPSC stands for Herschel SPIRE Point Source Catalog, www is one of
[250,350,500], identifying the wavelength in microns, and the letter A
indicates the first public version of the catalog.
In the case of the planets the sequence is formatted as ppp_000,
where ppp stands for one of the strings URA or NEP indicating Uranus or
Neptune respectively, followed bya running number 000 indicating
the observation.
Note (G2): T when a warning if any of the known contributors to the catalog
object is within a rectangle defined by the tracklet of a known asteroid at
the time of the observation of the respective map, and the beam FWHM at the
wavelength of the map
