FLIX: Flux Limits from Images from XMM-Newton

FLIX is an upper limit server for XMM-Newton data, provided by the XMM-Newton Survey Science Centre (SSC).

Update 2016 Mar 29: a version of FLIX using the 3XMM (DR5) data products is now available from Flix for 3XMM (DR5).

If you provide a position of interest on the sky (or a text file with a list of positions) FLIX scans the public data products from XMM-Newton to determine whether each point was observed. If so FLIX:

Results are returned in the form of HTML tables and as a downloadable FITS file. For further information on input and outputs, see the online FLIX help file


Enter either: RA and DEC of point of interest For example:  12:34:56 -12:34:56 optional identifier
Or: Text file with one position per line:

Detection likelihood threshold for upper-limits (default 10.0 means ≈ 4-sigma, see help for more details)

Radius of circle [arcsec] for the flux estimation
For HTML output: select energy bands for upper-limits
0.2-0.5 keV0.5-1.0 keV1.0-2.0 keV2.0-4.5 keV4.5-12 keV
band 1 band 2 band 3 band 4 band 5
band 6 band 7
band 8
  band 9  
And select energy bands for encircled flux and error
0.2-0.5 keV0.5-1.0 keV1.0-2.0 keV2.0-4.5 keV4.5-12 keV
band 1 band 2 band 3 band 4 band 5
band 6 band 7
band 8
  band 9  
           

Thumbnail images: none 2 4 8 16 (arcmins)

Image overlays: none circle at specified position also 2XMMi sources and SRCID numbers

Show nearest field centre when position is not in field-of-view yes no            

(Note: FLIX may take several seconds per source position, please be patient).

This version writes a row to the FITS file even if there are no data from XMM-Newton for the specified position, so that for a list of N positions, there will be at least N rows in the FITS file produced.
