Notes. We note that the number of O stars indicated here is not completeness-corrected. tmax indicates the age of the oldest cluster in each region (fiducial value of 50 ± 25 percentile of the age PDF; masking cluster with ages > 10 Myr). In the case of region 5, which is hosting exclusively O stars, we have assumed 3 Myr as an upper limit for the age. The indicated E(B − V) is the median extinction in the region (estimated from the Balmer decrement). The total L(Hα) in each region is reddening corrected. Regions are classified as described in Sect. 6 into ‘classical’ ionisation bounded regions (IB) and regions featuring optically thin channels (CH).
