(a) ϵ Indi A imagewith injected planets at a contrast of 10⁻⁴ with a separation from 1″ to 2.5″ marked with white arrows to left. On the right-hand side is a likely false positive identifiedfrom an examination of the odd-even frames. (b) S/N map showing injected planets appearing with the S/N in the 5–7 range. The approximate position of ϵ Indi Ab is shown by a circle, but the uncertainties are large (for details, see Feng et al. 2019).
