[O iii]₈₈ distribution modeled around each star with an homogeneous density ranging from 2 cm^-3 to 256 cm^-3. The yellow polygon indicates the PACS coverage and the green polygon indicates the approximate extent of the optical body. The cyan circles in the n = 16 and 32 cm^-3 panels represent the extent of the [O iii]-emitting zone when considering a cluster instead of the individual stars (see text).
