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)

robs is the observed radius of the Hii region.

(7)

ne 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.

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.
