3XMM-DR8 data tables

• 3XMM_DR8cat_v1.0.fits.gz — full catalog in FITS format; recommended for more in-depth studies (includes information of all detections); 332 columns, 775 153 rows, 644 MB
• 3XMM_DR8cat_v1.0.csv.gz — same as above, but in CSV format; 698 MB
• 3XMM_DR8cat_slim_v1.0.fits.gz — reduced version of the catalog in FITS format, suited for studies of unique sources (individual detection information is not included); 44 columns, 531 454 rows, 69 MB
• 3XMM_DR8cat_slim_v1.0.csv.gz — same as above, but in CSV format; 77 MB

3XMM-DR5 footprint (MOC files)

Note that these are preliminary files computed from combined images for pixels that have at least one count in them, hence with small gaps; in future there will be more compact files computed from exposure maps.

• 12 order (pixel size 51.53", area 1191 sq. deg., file size 2.5 MB)
• 13 order (pixel size 25.77", area 1144 sq. deg., file size 6.7 MB)
• 14 order (pixel size 12.88", area 1066 sq. deg., file size 89 MB)
