WebApr 15, 2011 · The aperture photometry (IRAF phot task) is obtained using a circular extraction region of 5″ for the source and an annulus with inner/outer radius of 5.5″/6.25″ for the background. The script also extracts the publically available light curves of Fermi LAT, 8 Swift BAT, 9 and Swift XRT 10 of the AGNs. Webaperture photometry using IRAF/phot by using a few aperture sizes and eventually choosing a radius of 10 pixels (3. ′′ 04), resulting in the smallest scatter in the final light curves of the target and similar brightness stars, within 1 mag from that of the target.
