XSA version 10.1: New
The XSA v10.1, released on 25 July 2018, includes among other improvements the following implementations:
- Access to 3XMM-DR7s, the new Stack Catalogue based on 3XMM-DR7.
- Results of searches of the 3XMM-DR7s Stacked Catalogue allow two display options: it is possible to either display only the stacked sources or to display as well the individual observations with the parameters of the individual detected sources. Stacked Catalogue sources are linked to corresponding 3XMM sources, if already detected.
- Since XSAv10.1 the observations that have non-standard ODF, or that have PPS products with no science data, are not displayed in the Results panel unless they are specifically selected in the Search panel.
- The XSA TAP schema has now a more user friendly view of the ADQL query parameters.
XSA version 10.0:
The XSA v10.0, released on 16 May 2018, includes among other improvements the following implementations:
- Access to the new incremental EPIC (3XMM-DR8) catalogue.
- Searches on the 3XMM-DR8 catalogue are performed by default with Quality flag < 2 (i.e. sources "good" or "sources with suspect parameters"), and with Detection maximum likelihood (DetML) ≥ 10. These parameters can be changed in the main search panel.
- The replacement of DS9 by JS9 as image viewer for the Interactive Data analysis functionality RISA. JS9 is integrated in the Web browser and therefore does not require the use of SAMP for the interactive data analysis. Feedback and suggestions for future RISA options (via the XMM-Newton helpdesk) are encouraged and appreciated.
- Radiation Monitor files can now be searched and downloaded from the XSA interface.
XSA version 9.8:
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.
