Release of the Herschel/SPIRE Point Source Catalogue
Posted by h schelp on 08 February 2017 08:55 AM

Dear Herschel colleagues,

We are pleased to announce the public release of the SPIRE Point Source Catalogue (SPSC), containing more than 1.6 million entries spread between the three SPIRE bands.

The distribution of the detected sources in the sky and other top-level information about this catalogue can be found on the SPSC web page at:

https://www.cosmos.esa.int/web/herschel/spire-point-source-catalogue

The catalogue consists of three tables, one for each SPIRE photometric band, provided as zipped coma-separated-value format files, that you can download with just one click using the links below: 

For your convenience, you can also perform queries around a particular position in the sky using the Catalog Search Tool for Herschel data available from NASA's Infrared Science Archive (IRSA).

SPIRE mapped about 9% of the sky in submillimeter broad-band filters centered at wavelengths of 250, 350, and 500 microns (1199, 857, and 600 GHz, respectively), with spatial resolutions of 17.9", 24.2" and 35.4”, respectively. The SPSC was extracted from a total of 6878 Herschel observations, consisting of a serendipitous mix of program science observations with sky coverage to varying depths and calibration observations performed in standard configurations.

The 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 catalog 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 the SPSC construction, detailed content, guidelines, and validation, please see the SPIRE Point Source Catalogue Explanatory Supplement. Users should pay particular attention to the Cautionary Notes in this document before using the contents of the SPSC for their research.

Kind regards,

A revamped web-based user interface for the Herschel Science Archive (HSA 8.0)

A new version (v8.0) of the Herschel Science Archive (HSA) has been released, offering a completely revamped web-based user interface, improved performance and a better user experience.

The new web interface incorporates all the functionalities previously provided by the old Java-based interface, plus some new ones like:
 - a better separation of the different type of Herschel data products available, currently consisting of Standard Pipeline Generated (SPG) products and User Provided Data Products (UPDPs), both for making queries and in the way the results are displayed;
 - visualization of the accurate footprints projected onto the Digitized Sky Survey (DSS) image of the field;
 - a new search functionality based on associated refereed publications, providing links to the Herschel data used for these publications and to the corresponding publication registry in ADS, including the possibility to search for observations in the archive without known publications;
 - on-the-fly generated basic statistics of the results obtained, presented as histograms in a dedicated window and updated interactively as you refine your query.

You can access the new interface at:

http://archives.esac.esa.int/hsa/whsa/


HSA now fully populated with legacy pipeline products

In the last few months we have completed the final bulk reprocessing of the whole contents of the Herschel Science Archive (HSA) using a set of different HIPE 14 versions of the software (14.1, 14.2.0, 14.2.1 or 14.2.2, depending on the instrument and observing mode).


This means that the HSA is now populated with the final 'legacy' products generated in an automated fashion by the Herschel SPG pipelines.

No further pipeline reprocessing is envisaged, therefore any further addition to the contents of the archive in the future will come in the form of interactively generated Highly Processed Data Products (HPDPs), enhanced products provided by experts in the Herschel ground segment, or as User Provided Data Products (UPDPs), collected from inputs provided by the community, an area on which we will be concentrating our efforts in 2017, the last year of Herschel Post-Operations.

An overview of the wide range of Herschel Data Products distributed (or to be distributed soon) through the HSA can be found at:

https://www.cosmos.esa.int/web/herschel/data-products-overview



Legacy version of the Herschel data reduction and data analysis software (HIPE 15.0) released 

We are pleased to inform you that a new version of the Herschel Interactive Data Processing Environment software (HIPE 15.0) is available for download at:

https://www.cosmos.esa.int/web/herschel/hipe-download

Together with the installers for the various operating systems that we support you can also find in this web page updated documentation applicable to this version of the software.

Note that no further development related to HIPE is planned for the remaining Herschel Post-Operations. HIPE 15.0 must therefore be considered the 'legacy version' of the Herschel data reduction and data analysis software.

For information about 'What's New in HIPE 15.0' you can visit:

http://herschel.esac.esa.int/twiki/bin/view/Public/HipeWhatsNew15x#Highlights

Please, let us know through the helpdesk if you have any problems during the downloading/installation process, or with any other aspect of this new version of HIPE and we will assist you.


The European Far-Infrared Space Roadmap

The initiative that led to the 'European Far-Infrared Space Roadmap' was borne out from discussions in the Herschel Users' Group (HUG). The work started in early 2015 and the first draft was prepared in the spring of 2016. It was presented to the community in the EWASS 2016 Symposium S4 'Future Prospects for Far-Infrared Space Astrophysics' held in Athens in July 2016, and made generally available. The work was concluded in late 2016, taking feedback received into account, and the Roadmap was posted on arXiv in January 2017.

The 'European Far-Infrared Space Roadmap' is available here:

https://arxiv.org/abs/1701.00366

"Exploiting the Herschel Science Archive" Workshop, 25-28 October 2016 - material available on-line

The PDF files and the video recording of all the presentations that were given at the "Exploiting the Herschel Science Archive" on-line Workshop, held on 25-28 October 2016, featuring the legacy contents of the Herschel Science Archive, are now publicly available at:

http://herschel.esac.esa.int/twiki/bin/view/Public/ArchivalWorkshop2016

The workshop was targeted at the community of Herschel users interested in archival research, with demonstrations of the various existing data mining tools, including a guided tour on the legacy of the Herschel mission with the goal to maximise the science exploitation of processed products in the Herschel Science Archive.

New User Provided Data Products (UPDPs) available

We continue collecting new sets of User Provided Data Products (UPDPs) from the community. They are served through the Herschel Science Archive user interface, which can be reached at:

http://www.cosmos.esa.int/web/herschel/science-archive

The latest addition is:

* PRISMAS: (PRobing InterStellar Molecules with Absorption line Studies): a comprehensive spectroscopic study carried over with HIFI and PACS of key molecular line carriers, probing interstellar hydrides (some 25 different molecules towards 10 sources) and carbon chains in our Galaxy. It took advantage of the strong dust emission from massive star forming regions to detect multiple absorption components from foreground clouds of diverse properties, known to intersect the selected lines of sight, along with emission and absorption intrinsic to the background sources.

You can find more information on this UPDP at: http://archives.esac.esa.int/hsa/legacy/UPDP/PRISMAS/prismas-release-note-v2-lo.pdf

The number of UPDPs served by the HSA is gradually increasing. The full list of available UPDPs at any time can be found at:

http://www.cosmos.esa.int/web/herschel/user-provided-data-products

Please contact the Herschel Science Centre Helpdesk if you have any question or if you need assistance on how to deliver your own User Provided Data Products.

New Highly Processed Data Products (HPDPs) available

As part of the continuous effort to improve the legacy contents of the Herschel Science Archive we are also embarked in the generation of Highly Processed Data Products (HPDPs), which are enhanced products with respect to what the automated processing pipelines can produce. These data sets are generated in a combined effort by experts at the Herschel Science Centre, the NASA Herschel Science Center and the Instrument Control Centres using interactive data reduction techniques, improving the quality or adding value to the products generated by the pipelines.

The list of HPDPs currently foreseen for the three instruments are compiled and made available at:

http://www.cosmos.esa.int/web/herschel/highly-processed-data-products

As of today, the following HPDPs have already been prepared and made available at the above web page:

1. Highly Processed HIFI Spectral Maps in the range 1410-1910 GHz - Available from the Herschel Science Centre and IPAC/IRSA.

Spectral mapping observations taken with Herschel/HIFI in Bands 6 and 7 (1410-1910 GHz) have been processed to highest fidelity using the final pipeline (v14.1.0) and calibrations, and interactive methods to most effectively treat baseline artifacts, co-add data, and optimize spectral cube gridding. These Highly Processed Data Products (HPDPs) provide the community interested in very high velocity resolution maps at these frequencies, covering [C II], [N II], high-J level CO and hot water transitions, with the nearest-possible to science-ready advanced data products without requiring HIPE. The products include the spectral cubes, spectral averages, and integrated line intensity maps in FITS format for ~450 science and calibration observations, as well as improved browse images to more readily reveal the scientific potential of the high-quality maps, which may have been missed by the original programme investigators.

The products are available for download as zipped tar archives at the Herschel Science Centre's HPDP webpage (see link above), and can also be browsed and downloaded on an observation basis from the NASA InfraRed Science Archive (IRSA, http://irsa.ipac.caltech.edu/Missions/herschel.html).

More information at: http://archives.esac.esa.int/hsa/legacy/HPDP/HIFI/HIFI_spectral_maps/HPDP_Release_Note_v1.1.pdf

2. HIFI reference positions spectra

This data-set provides a stand-alone collection of isolated spectra taken at the reference positions used to perform the vast majority of the HIFI observations. Although these products exist embedded in the observation contexts of each observation, this data-set allows an immediate inspection, and if applicable, further correction, of the reference spectra with no need to download the calibration context of a given observation. One particularity of this data-set is also that reference positions used in raster mapping and spectral scan observations are provided as data cubes and deconvolved spectra respectively, allowing direct comparison with the ON-target counterparts.

More information at: http://herschel.esac.esa.int/twiki/pub/Public/HifiDocsEditableTable/HIFI_ReferencePositionSpectra_HPDP_ReleaseNotes.pdf

3. HIFI flux calibration uncertainty budget tables

This data-set consists of a stand-alone collection of the HIFI flux calibration uncertainty tables provided as embedded products inside the HIFI observation contexts. Each table offers a detailed flux calibration uncertainty budget at the applicable observing frequency, as well as the combined error to quote for error bars on the extracted line or continuum intensities.
