ISO Data Archive Software Upgraded to Version 6.0
25 July 2003In the afternoon of the 24th of July 2003, a new version (v6.0) of the ISO Data Archive (IDA) software was installed. This upgrades the functionality associated with, and visibility of, the Highly Processed Data Products - data reduced systematically 'by hand', and allows for continuous ingestion of ISO catalogues and atlases from the community.
The Off-Line Processing Pipeline copes well with a number of instrumental artifacts in an automatic fashion. The final products, available from the ISO Data Archive, can however be improved by processing them further, in particular by means of the Interactive Analysis software packages, as documented in the ISO Handbook. The resulting products are called Highly Processed Data Products (HPDP). In a broader sense this definition includes catalogues and atlases. These sets are therefore inhomogeneous in nature, but their presentation is made as uniform as possible.
Version 6 of the ISO Data Archive allows for continuous ingestion of new HPDP sets. An up-to-date list of HPDPs is created on-the-fly from the IDA using the dedicated link in the ISO Home Page, also upgraded with this release to evidence this new kind of archived products.
How to query HPDP and catalogues
Open the Highly Processed Data Products panel (located below the main search panel). Sets of HPDP can there be queried against author and title. Combined queries with any other panels are also possible.
A separate panel allows to query on any given catalogue. A description of each catalogue can be obtained by clicking on the title, coloured in blue. Having selected the catalogue to query, a dedicated query panel will be created on-the-fly. A descrition of each catalogue column can be obtained by clicking on the column name, coloured in blue.
As for any IDA query, the result will be a list of observations. Observations having HPDPs will have the "HPDP" button on the left highlighted.
How to access HPDP data and info
In the query results panel, as for any other product, the HDPD can be retrieved directly on disk by pushing "Retrieve" and selecting "HPDP". For more information and features, click on the highlighted HPDP button at the left of any given observation. This will lead to a new panel. Abstracts will be given of all HPDP sets containing the observation. Six buttons on the left will lead to:

About the ISO Data Archive
ISO was the world's first true orbiting infrared observatory. With four highly-sophisticated scientific instruments and a pointing accuracy at the arc-second level, ISO provided a facility of unprecedented sensitivity and capabilities for exploring the Universe at infrared wavelengths from 2.5 - 240 microns. During its highly-successful in-orbit operational phase from November 1995 to May 1998, ISO made some 30 000 individual scientific observations of all types of astronomical objects, from within our own Solar System out to the most distant galaxies. The resulting database provides a treasure trove of information for further astronomical research.
All data is available to the community via the ISO Data Archive and from an increasing number of suppliers of astronomical information (Virtual Observatories).
The ISO Data Archive (IDA) has been on-line since December 1998. It was designed and developed at the ISO Data Centre, in continuous and fruitful cooperation between users and developers, providing a unique, state-of-the art astronomical data archive.
