Proper motions of stars in the FOV. Red-coloured diamonds denote hot star candidates we classified as being located in the GC, as listed in Table E.5, and blue cross-symbols denote those hot stars we classified as non-GC stars or stars with unknown status. The black arrows indicate the proper motions of hot star candidates from Shahzamanian et al. (2022). The arrow lengths are multiplied by a factor of 3000 for better visualisation. The grey arrows are a subset (2.5%) of the Shahzamanian et al. (2022) proper motions to illustrate the distribution of proper motions in this region. Black dashed lines denote the approximate outline of our FOV, blue dashed lines the region shown in Fig. 8. The purple circle denotes Quintuplet’s tidal radius r_t ∼3 pc (Rui et al. 2019), the green solid circle denotes the NSC R_e = 5 pc. The x-axis and y-axis have different scales; therefore, the circles and proper motions appear elongated along the y-axis.
