F160W NICMOS field from 1998 as processed by the ALICE pipeline (Choquet et al. 2014; Hagan et al. 2018). Since the ~25-year orbital period of AF Lep b is comparable to the 24-yr difference between these HST observations and our new data, the planet probably lies at a similar position relative to the star in both data sets. However, we do not expect a detection of the planet with HST NICMOS because the occulting spot has radius 0″.3 and the contrast needed to achieve a detection begins past 0″.5 radius from the star. The white box indicates the expected position of the companion in this 1998 epoch if it were a stationary background star instead of a common proper motion companion.
