The origin and evolution of the [CII] deficit in HII regions and star-forming molecular clouds

Table 2

Time at which the first massive star (M > 8 M_⊙) forms (from the beginning of the simulation) and conversion between t_evol and t_sf.

Cloud	t_sf,o [Myr]	t_evol → t_sf
MC1-HD	13.75	t_sf = t_evol − 1.85 Myr
MC2-HD	13.60	t_sf = t_evol − 1.70 Myr
MC1-MHD	19.34	t_sf = t_evol − 3.34 Myr
MC2-MHD	18.10	t_sf = t_evol − 2.10 Myr

Notes. For MC1-MHD, the first snapshot, at t_evol = 3 Myr, is before the onset of star formation.
