FITS image Exposure map (J2000): An image of the time (in seconds) spent observing within the GALEX field of view (no response correction).
-fg-int.fits.gz
-ng-int.fits.gz
FITS image Intensity map (J2000): Photons per pixel per second corrected for the relative response. Note that "-int.fits" is equal to "-cnt.fits" divided by "-rrhr.fits".
-fg-skybg.fits.gz
-ng-skybg.fits.gz
FITS image Sky background image (J2000): Photons per pixel per second estimate of the background. This background is subtracted from the intensity image which is then used for source detection.
-fg-rrhr.fits.gz
-ng-rrhr.fits.gz
FITS image High resolution relative response (J2000): Effective exposure time per pixel upsampled from the -rr.fits image.
-fg-wt.fits.gz
-ng-wt.fits.gz
FITS image Weight/threshold image (J2000): Used by SExtractor for thresholding sources. Pixels > 1 are above the detection threshold. This image is derived by dividing the background-subtracted intensity by a detection threshold image.
-fg-intbgsub.fits.gz
-ng-intbgsub.fits.gz
FITS image Background subtracted intensity map (J2000): Intensity map image with the background removed (used for source detections). Note that "-intbgsub.fits" is equal to "-int.fits" minus "-skybg.fits".
-rtastar.fits FITS table Star catalog used for attitude refinement.
