Position and motion of the found runaways relative to NGC 6618, with the DSS2 B, R, and I colour image and the Very Large Telescope Survey Telescope OmegaCAM image (ESO/INAF-VST/OmegaCAM). We show the proper motion of the runaways relative to NGC 6618 with the arrows, which are proportional to their absolute proper motion. Runaways which are consistent with being O stars in Table 2 are coloured in blue, and coloured red otherwise. We show the position of NGC 6618 (PG) and M 17 (EB) using white circles. The angular size equivalent to 10 pc is given at the distance of NGC 6618 (1674 pc).
