Density map of the LMC East periphery, constructed by adopting only MSTO stars of an intermediate-age (7 ≤ t ≤ 9 Gyr, left panel) and old (t ≥ 10 Gyr, right panel) stellar populations. Specifically, we picked up stars within the colour and magnitude range of 0 ≤ g − i ≤ 0.5 mag and 21.4 ≤ g ≤ 21.9 mag for the younger stellar population, and 0.1 ≤ g − i ≤ 0.6 mag and 21.9 ≤ g ≤ 22.4 mag, for the older one, respectively. Each pixel has size of 5′×5′ and we adopted a Gaussian Kernel Density Estimator with bandwidth = 0.25° to smooth the plot.
