Notes. Here θcore indicates the source size, Eq. (12); 
the dust and gas masses, Eq. (13); 
the hydrogen density, Eq. (14); 
the electron density, Eq. (15); 
the ionized gas mass, Eq. (16); 
the number of ionizing photons per second, Eq. (17); 
the initial Strömgren radius, Eq. (19); 
the isothermal sound speed, Eq. (21); 
the dynamical age of a H II region, Eq. (20); and 
the ratio of the electron to molecular pressure, Eq. (22). The values in parentheses indicate the values obtained by Sánchez-Monge et al. (2017). For sources marked with an asterisk (*), we could not derive a self-consistent description of the continuum of the corresponding core spectrum.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
