Note: This model grid, put online on 10-Apr-2026, replaces the previous version which, for reference, is still accessible by choosing "WNE-2016" in the drop-down menu. In the 2026 version the treatment of the iron group elements has been improved to reduce a pronounced violation of the energy conservation. Now, (PoWR version from 19.02.2018) the emissivity scales over an iron superline according to a Boltzman factor with max(T(r),Teff) instead of always T(r).
However, for the following models a larger iron data file (doubled the
number of superlevels by bisecting each energy band) was used:
15-17 15-18 15-19 15-20 15-21 16-18 16-19 16-20 16-21
| Ion | No. of levels | |

| G XIII | 0 | 15 |
| G XIV | 0 | 14 |
| G XV | 0 | 10 |
| G XVI | 0 | 9 |
| G XVII | 0 | 1 |
Notes: Element "G" stands for the generic iron-group element,
which combines the elements from Sc to Ni in solar relative mixture.
In case of the "G" element, the number of levels given in the above table
actually refers to superlevels. If two
entries are given for the same "G" ion, the first one refers to the
cooler part of the model grid and the second entry to the hotter part
(T* of 100 kK and higher)
For the above mentioned particular models the number of iron superlevels is twice the number
that is given in the table.
For a couple of lines, contour plots of the equivalent width have been prepared. The contours are labeled with Wλ in Angstroem:

The following contour plot relates the stellar temperature T, which refers to the hydrostatic radius, to the "effective" temperature T2/3 referring to the radius of the optical depth 2/3. The contours are labeled with log T2/3 in Kelvin.

The corresponding contour plots for the outdated 2016 version of the WNE grid can still be found here for reference.
