XSA version 9.8: New
The XSA v9.8, released on 15 February 2018, includes the following improvements:
- A new design of the main (Search) panel.
- Links to ESASky to explore the observation or source region in other wavelengths.
- An upgrade to the Table Access Protocol TAP+ to access the XSA database.
XSA version 9.7:
The XSA v9.7, released on 25 October 2017, includes the following improvements:
- A new database column with RA in decimal degrees instead of decimal hours. This is now used to send ObsIDs coordinates to VO tools like Topcat. Coordinates in decimal degrees can also be used to search observations through the Table Access Protocol (TAP).
- Publications using slew observations can be searched and displayed.
- For a "Search on a File" it is now possible to get the list of all resulting Observation IDs.
- The XSA interface is now working also with the Internet Explorer web browser.
- It is possible to use a bibcode to search for all observations used in a specific publication (e.g. http://nxsa.esac.esa.int/nxsa-web/#bibcode=2013A%26A...558A...3S).
XSA version 9.6:
The XSA v9.6, released on 26 July 2017, includes the following improvements:
- Generation and display of postcards for Finding Charts and Spectra of EPIC PPS sources.
- Option to download PPS products of moving targets, i.e. Solar System targets, generated in their rest frame coordinates, in parallel to the standard PPS products of these observations.
XSA version 9.5:
The XSA v9.5, released on 1 June 2017, includes the following:
- access to the new incremental EPIC (3XMM-DR7) catalogue.
- in the XSA the searches on the 3XMM-DR7 catalogue are performed by default with Quality flag < 2 (sources good or sources with suspect parameters), and with Detection maximum likelihood (DetML) ≥ 10. These parameters can be changed in the main search panel.
XSA version 9.4:
The XSA v9.4, released on 9 May 2017, includes among other improvements the possibility to perform on-the-fly data processing with SAS, through the Remote Interface for Science Analysis (RISA) server, without the need of downloading data and software. The on-the-fly data processing in this release is an experimental version, intended to allow the community to test it and provide their feedback. Known issues and possible workarounds are described in the watchouts section, which will be updated if needed.
The data analysis options, presently only available for public observations, include:
- Extraction of spectra and light curves of sources interactively defined in an EPIC exposure image displayed on a DS9 window.
- Background filtering of EPIC events files of an EPIC instrument exposure using a user-defined count rate.
- Extraction of EPIC images in user-defined energy bands.
- Reprocessing of an observation ODF with latest SAS and calibrations.
- Reprocessing of an individual source with latest SAS and calibrations, obtaining spectrum, background, ancillary (ARF) and response matrix (RMF) files (*).
(*) Note that the current pipeline is fully aligned with the most recent SAS and calibration. Hence, reprocessing a recent ODF will produce no difference with regard to Pipeline products in XSA which can be directly downloaded.
For data processed before 31 January 2017, note that the last full reprocessing of the archive was performed mid 2013. Please check the pipeline web page to see pipeline release dates between this last full reprocessing and today.
XSA version 9.3:
The XSA v9.3, released on 20 March 2017, includes, among other improvements and bugs fixed, the following:
- access to the new version of the XMM-Newton SLew Survey Catalogue (XMMSL2)
- access to the updated version of the XMM-Newton OM Catalogue (XMM-SUSS3.0)
- public ODFs and PPS products can individually be downloaded without the need of login into XSA. The use of the shopping basket for multiple downloads still requires to be logged in
- display of the new pipeline products for EPIC PPS sources (postcards with extraction regions and combined light curves)
- possibility to customise coordinates and distance units in the results panels
XSA version 9.2:
The XSA v9.2, released on 30 November 2016, includes, among other improvements and bugs fixed, the following:
- new functionalities for the shopping basket.
- postcard OM images for all filters used in the observation.
- display of Slew Survey PPS sources (at the time of the XSA v9.2 release the pipeline is not producing slew sources yet. It is planned that the next pipeline version will do so).
- checkboxes added to all sources in the results page (to allow saving or broadcasting source lists).
XSA version 9.1:
The XSA v9.1, released on 5 July 2016, includes the following:
- access to the new incremental EPIC (3XMM-DR6) catalogue.
- a new display of results for the search on a list of objects.
- improvement of the name resolver when searching by name.
- the observations results table includes information about coordinated observations.
XSA version 9.0:
The XSA v9.0, released on 3 May 2016, includes among other improvements and bugs fixed, the following:
- New columns can be selected to be displayed in the different Results tabs.
- OM combined images are shown in the Details panel besides EPIC and RGS combined images, and can also be displayed in the Observations results panel.
- The new pipeline product EPIC 3 Colour Image is shown instead of the old EPIC combined image when available.
- More command line and URL options to access XSA data are provided (see: http://nxsa.esac.esa.int/nxsa-web/#aio).
- New XSA TAP (Table Access Protocol) implemented to be able to access the XSA database info (see: http://nxsa.esac.esa.int/nxsa-web/#tap).
- Links to XcatDB info are provided for 3XMM-DR5 sources.
