资源简介:

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 shape: standard "agn.sed", a continuum similar to Mathews & Ferland (1987) The Fe II template is available for the microturbulence values 0,10, 20, 30, 50 and 100 km/s. (Note: The Fe II templates for the inward (directly illuminated) and outward (shielded) emissions are also available in the GitHub link: https://github.com/Ashwani-88/Fe2_template) Each tar.gz file consists of Fe II templates for a microturbulence velocity and is named as turb_vn.tar.gz, 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−2s−1,b = log value of the Hydrogen gas density in cm−3, andc = the value of microturbulence in km/s. Each template file has two columns First column: wavelength in Angstrom with 2 Angstrom binningSecond column: Fe II line intensity (in erg cm-2 s-1)
