The compressed '.tar.gz' files contain new theoretical Fe II templates that can be used for fitting UV to near-IR (1000-10000 Angstrom) spectra of quasars. The templates were developed using the latest Fe II atomic database of Smyth et al. (2019) within the CLOUDY C23.0 photoionization code with the following set of parameters.
H-ionizing photons flux: 17 ≤ log ΦH (cm−2 s−1) ≤ 22, and
Gas density: 9≤ log nH (cm−3) ≤ 14,
Step size: 0.25 on log scale.
A fixed Hydrogen column density: 10^24 cm−2
Abundance: solar
SED shapes:
(1) Standard "agn.sed", a continuum similar to Mathews & Ferland (1987)
(2) Intermediate SED of (Jin et al., 2012)
The Fe II template is available for the microturbulence values 0, 20, 50 and 100 km/s.
(Note: The Fe II templates are also available in the GitHub link: https://github.com/Ashwani-88/Fe2_template)
Each tar.gz file consists of Fe II templates for different SED shapes. For each SED shape;
The new Fe II templates are available in the directory "Templates_including_only_total_Fe2".
Additionally, we provide templates for the outward and inward Fe II emissions in the directory "Templates_including_outward_Fe2"
The directory for Fe II templates for a microturbulence velocity is named as
turb_vn
where n is the microturbulence velocity in km/s. The files within each directory are named as follows:
phia_nHb_mc.dat
where a = log value of the H-ionizing photon flux in cm−2 s−1,b = log value of the Hydrogen gas density in cm−3, andc = the value of microturbulence in km/s.
Each template file in ``Templates_including_only_total_Fe2'' has two columns
First column: wavelength in Angstrom with 2 Angstrom binning Second column: Fe II line intensity (in erg cm-2 s-1 A-1)
Templates in ``Templates_including_outward_Fe2'' has four columns.
First column: wavelength in Angstrom with 1000 logarithmic bins, each ~ 584 km/s wide, between 1000 and 7000 Angstrom. Second column: Total Fe II line intensity (in erg cm-2 s-1 A-1) Third column: Inward Fe II line intensity (in erg cm-2 s-1 A-1) Fourth column: Outward Fe II line intensity (in erg cm-2 s-1 A-1)
The Fe II line intensity includes a covering factor of 30 % and is scaled for our test object RM 102.
