The background estimation process used for aperture photometry. Left: a circular annulus is placed at the measured source position (red x), with bad pixels shown in white. Middle: pixels outside of the annulus (and if necessary, those containing sources) are ignored. Right: a histogram of the resulting pixel values. The background is estimated as the sigma-clipped mean of these values (orange line).
