Absolute G magnitude versus orbital period for tight system candidates (samples 2G-B, 2G-C, 2GE-B, 1GE and 0GE) with global ranking higher than 0.5 (> 0.45 for Sample 2G-B). Sources with relative parallax uncertainties better than 10% in the Galaxy are shown in grey and sources towards the LMC (same selection criteria as in Fig. 42) are shown in red. A distance modulus of 18.476 mag is adopted from Pietrzyński et al. (2019) for the LMC.
