5′ ×5′ archival images with the SPOC photometric aperture over-plotted in orange, the Gaia DR2 position (J2015.5) of π Men indicated by a red square, and other Gaia DR2 sources within 2′ of π Men indicated by circles. The magenta circle indicates the position of Gaia DR2 4623036143819289344, a nearby source bright enough to be the host of the observed transit signals (see Sect. 3), and cyan circles indicate sources that are too faint.
