Watchouts

 

 

  • Since XSAv10.0 the on-the-fly data analysis (RISA) functionality includes a limited number of data analysis possibilities. We invite the community to test it and let us know via the XMM-Newton helpdesk about their results and suggestions for future improvements.

  • Radiation Monitor files available from the XSA archive are being produced regularly but not every revolution has these files available, and there might be delays in the production of the files for the last revolutions.

  • Search on a file with a list of names or positions is currently limited to about 1000 entries. A possible workaround to perform a search on a larger list is to use TOPCAT or CDS Xmatch to cross-match your list with the complete list of XMM-Newton observed positions, which can be downloaded from XSA, from Vizier or from the XSA observations log.

  • The observations performed in mosaic mode have a global Observation Data File (ODF) which is also split into 'pseudo ODFs' (see Chapter 2 of the Data Files Handbook).
    The ObsID of all 'pseudo ODFs' belonging to a mosaic have the first 8 digits in common (e.g. 06730001). Split 'pseudo ODFs' can be recognised because the last two digits of their ObsIDs are not 01 but 31, 32, 33, etc. (e.g. 0673000131, 0673000132 etc). Note that the data (i.e. the X-ray events) of the 'pseudo ODF' subsets has been extracted from the global ODF (i.e. the same data for the sky area covered in the pseudo ODF). Pseudo ODF subsets should therefore never be combined or merged with the global ODF.

  • JS9 display functionalities can be used for on-the-fly visualization of the PPS files in the list "Open FITS file with JS9". For "EPIC Events" it is convenient to bin the image by selecting View -> Bin/Filter/Section and typing for example bin=32 in the pop-up window. Then click "Run", and "Load full image" to view the entire "EPIC Events" image.    New

  • To overlay (blend) or blink more than one image loaded in JS9, say an EPIC combined image and an OM image, you can first sync the display commands using:
          File -> sync ... -> sync images ... -> all images
    and then re-project the OM image to the EPIC image using:
          WCS -> wcs reproject -> all images in this display.
    Then, for example, blink the EPIC and OM images with:
          View -> Blinking

    Note: if you zoom or pan any of the images, you need to deselect and select again the images in the Blinking form, for the commands to apply to all loaded images.   New



Notes on the XSA releases

 

XSA version 11.5:    New

The XSA v11.5, released on 20 Nov 2019, includes among other improvements the following:

  • Adapt to the new ads publications format
  • Preparation for the ingestion of the bulk re-processed Pipeline products (PPS)
  • Disable the reprocess options, as bulk reprocessed products will be up-to-date

XSA version 11.4:   

The XSA v11.4, released on 05 Nov 2019, includes among other improvements the following:

  • More functionalities for the Results Display of "Search in a File":
    • It is now possible to display all together the results of searching a list of objects, which is particularly useful to find the PPS or catalogues sources found for the given list of positions.
  • Footprints have been refined for "Search in the FOV".
  • More functionalities for the on-the-fly JS9 image visualizer:.
    • Possibility to visualize, with JS9, the EPIC or OM image products without the need to download them previously. JS9 functionalities (similar to DS9) can then be used.
    • Possibility to overlay (blend), blink, etc, of EPIC and OM images.
    • Possibility to overlay on EPIC images the sources detected by the pipeline.
  • The TAP QUERIES help Tab has been re-designed including more detailed examples of TAP queries via Command line.

XSA version 11.3:   

The XSA v11.3, released on 06 Aug 2019, includes among other improvements the following:

  • More functionalities for the RGS Spectra Visualizer:
    • Larger sets of spectral lines available to overlay on the RGS spectra
    • Option to select/deselect the spectra to average, after plotting them
  • More functionalities for the JS9 image visualizer:
    • Possibility to visualize, with JS9, the EPIC or OM image products without the need to download them previously. JS9 functionalities (similar to DS9) can then be used.
    • Possibility to overlay EPIC PPS source regions on the images, and to identify them by their coordinates.
  • The INTERACTIVE ANALYSIS Tab now includes a more detailed help about these items and a video tutorial.

XSA version 11.2:

The XSA v11.2, released on 27 May 2019, includes among other improvements the following:

  • More functionalities for the RGS Spectra Visualizer:
    • Option to display 2 sets of spectral lines overlaid on the RGS spectra.
    • Option to plot the flux errors as error bars.
    • Option to use logarithmic scale for X axis.

XSA version 11.1:

The XSA v11.1, released on 25 April 2019, includes among other improvements the following:

  • More functionalities for the RGS Spectra Visualizer:
    • Plot all or the average of the RGS fluxed spectra of selected observations.
    • Select/deselect spectra from the list of obsIDs in the plot.
    • Convert plot units Wavelength/Energy.
    • Introduce redshift to display the spectrum in the rest frame.
    • Define x,y plot ranges.

XSA version 11.0:

The XSA v11.0, released on 14 March 2019, includes a new login system, managed via the ESA Cosmos Authentication System.

  • ESA Cosmos accounts have been created for those PIs that did not have it, and that have current or pending proprietary observations. Their account details have been provided by email.
  • Any other scientist without an existing ESA Cosmos account can register at:
        https://www.cosmos.esa.int/web/xsa/self-registration.
