Gaia colour-magnitude diagram of the systems with new common µ and π companions in Table 3. Blue circles, red triangles, and the green square stand for the main-sequence, subgiant, and white dwarf stars, while the small grey points are the over 50 000 random Gaia sources retrieved as Taylor (2021) did. The young overluminous star UCAC3 53–724 in Tucana-Horologium is labelled. The black solid line is the updated main sequence of Pecaut & Mamajek (2013). We did not apply any colour or magnitude correction for reddening.
