Example of the different apertures used by different surveys and our measurement in all the filters. The first image shows the galaxy in the SDSS u𝑔riɀ bands. The orange line represents 20″. This SDSS image is followed by FUV and NUV from GALEX; u, 𝑔, r, i, and ɀ from SDSS; and W1, W2, W3, and W4 from WISE. Cyan circles show the apertures shown on the GALEX catalogue. Magenta apertures show the small aperture listed in SDSS tables, which is barely seen in the figure. Red apertures are the listed ellipses in AllWISE tables. The aperture we use for all filters, in this case measured from the W4 image, is shown in green.
