Trumpler 14 cluster studied in this work. Grey sky image from HAWK-I H-band observations (Preibisch et al. 2011a,b) shows the whole region, with the light grey grid of MUSE pointings and stars studied in this work marked as red circles. The five panels above and on the right show selected MUSE I band images. The panel inside consists of a mosaic of four MUSE pointing of the Tr 14 centre. Their numbers are indicated in the panels. Positions of the stars on MUSE images are marked with empty grey circles. The bar on the lower right corner of the HAWK-I image indicates the projected distance of 0.5 pc at the assumed distance of 2.35 kpc towards Tr 14 (Göppl & Preibisch 2022).
