Notes.

^(a)

All values listed in this table are the values used in the different models assuming Hii regions are spherical symmetric regions of fully ionized gas with no dust and a single ionizing source.

^(b)

These regions are optically thick. Their electron density has been increased manually.

⁽¹⁾

ID is the identifier used in the model. We use the same identifiers as Mehringer et al. (1993), Gaume et al. (1995), De Pree et al. (1998).

⁽²⁾

Model refers to one of the four model described in this paper.

⁽³⁾

RA is the right ascension of the Hii region given in units of hours:minutes:seconds in the equatorial coordinate system.

⁽⁴⁾

Dec is the declination of the Hii region given in units of degrees:arcminutes:arcseconds in the equatorial coordinate system.

⁽⁵⁾

dz is the displacement along the line of sight with respect to the model center. The z-axis is oriented such that it points towards the observer.

⁽⁶⁾

r_obs is the observed radius of the Hii region.

⁽⁷⁾

n_e is the number electron density.

⁽⁸⁾

ZAMS refers to the zero age main sequence star embedded in the Hii region.

⁽⁹⁾

EM is the emission measure.

⁽¹⁰⁾

log() is the logarithm of the number of Lyman continuum photons.
