Guide to ISO Data Products: Highly Processed Data Products
Last Update: 25 January 2007
The Off-Line Processing Pipeline copes well with a number of instrumental
artefacts in an automatic fashion, as described in the ISO Handbooks.
The final products can however be improved by processing them further,
e.g. by means of the Interactive Analysis software packages. 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.
HPDPs marked in bold are the ones recommended as the "Best dataset".
How to query HPDP and catalogues
Open the Highly Processed Data Products panel (located below the main
search panel). A description of each HPDP set can be obtained by clicking
on the title. Select the HPDP via the tick box on the left and press
the general IDA "Execute query" button. Combinations with other query
panels are also possible.
For HPDP associated with a catalogue, the button "Search catalogue"
allows to obtain a query panel for the specific catalogue. A description
of each catalogue column can be obtained by clicking on the column title,
coloured in blue. Note that closing catalogue panels will *NOT* clear
the query specifications (the "search catalogue" button will change
to dark colour) - for this the button "Clear" should be used.
The result of the query
As for any IDA query, the result will be a list of observations.
If the query involves HPDPs, the observations will have the "HPDP"
button on the left enabled.
How to access HPDP data and documentation
In the query results panel, as for any other product, the HDPD can be
retrieved directly on disk by pushing "Retrieve" and selecting "HPDP".
HPDP associated to a given observation declared as "best" dataset will
Be delivered as "default dataset".
For more information and features, click on the enabled HPDP button at
the left of any given observation. This will lead to a new panel.
An abstract will be given of all HPDP sets containing the observation.
Six buttons will be displayed on the left:
-
Data
Clicking this button will allow to download the data directly.
-
Documentation/Article
This will generally be information stored in the IDA in the form of
a web page, launched by your default browser, with links to specific
documents or, as applicable, to the paper(s), via the ADS service.
-
Postcard
An illustration (plot, image) of the reduced observation. This
will be obtained by automatically launching your default browser.
-
Atlas
This is defined as an illustration of the observations together
with other information provided in the HPDP set, such as external
SEDs, stellar models, etc.
-
Catalogue
A new panel will be launched, pointing to the raw containing the
observation. The whole catalogue may be saved on disk or printed.
A (case-sensitive) search facility is also provided.
-
Add Related
Clicking this button will move all observations pertaining to the
given HPDP set to the shopping basket for retrieval in one go.
