Fig. 1: Examples of satellite trails identified in HST individual exposures and composite images.

a, Examples of satellite trails in individual HST ACS/WFC exposures (one aperture image, cutout FoV of roughly 101″ × 202″), with a typical integration time of 11 min: the first column shows typical trails (observation IDs j8cw52p3q and j8pu0hcfq); the second column shows multiple trails in an exposure (j8xi1bafq) and flickering satellite trail (jbhj04gcq) and the third column shows broad out-of-focus trail (ja4tg4lsq) and curved satellite trail (jcor25dtq). b, Imperfectly removed satellite trails in composite HST images, as identified by AutoML with bounding boxes in cutouts of HST composite images.
