This is a database containing all the HFR atomic data needed to compute the opacity of all neutral to trebly-ionized elements between Ca (Z=20) and Lr (Z=103) in the context of kilonova emission following neutron star mergers, as well as expansion and line-binned opacity tables for a grid of conditions, namely a time t = 1, 2, 3, 4, 5, 6, 7 days after the merger ; an ejecta density \rho = 1E-17, 1E-16, 1E-15, 1E-14, 1E-13 g/cm^3 ; and an ejecta temperature T = 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000 K. A table of Planck mean expansion opacities for all the elements is also provided for this grid of conditions. The details of the computations can be found in our paper: Deprince J. et al., "Kilonova ejecta opacity inferred from new large-scale HFR atomic calculations in all elements between Ca (Z=20) and Lr (Z=103)", in press (Astronomy & Astrophysics, 2025); arXiv:2412.16688 [astro-ph.HE]. The present data have been obtained in tight collaboration between the University of Mons (UMONS) and the University of Brussels (ULB), in Belgium. Note that the present version (v2) replaces version 1 (v1) that is obsolete. In this new version, we have corrected an error in the previous data for Pb (Z=82). Description of the files: 1) Atomic data: atomic-data-lanthanides includes the atomic data for all lanthanides ; atomic-data-actinides includes the atomic data for all actinides ; atomic-data-other includes the atomic data for all other elements from Z=20. All the three compressed files include two types of files, namely outglv and outggf files: outglv files: energy level lists. The first column gives the value of the energy level E_i (in 1000 cm^{-1}), and the second columns indicates the corresponding value of the total angular momentum J_i ; outggf files: transition lists. The three columns gives, for each line, the transition wavelengths (in A), the energy of the transition lower level E_i (in 1000 cm^{-1}), and the corresponding oscillator strength, gf. 2) Opacity tables : exp-opacity-table contains, for each element, the expansion opacity as a function of the wavelength for the above-mentionned grid of conditions. The first column gives the wavelength at which the opacity is computed, and the following ones correspond to the expansion opacities for the conditions (t,\rho,T) mentioned in the first three rows ; lb-opacity-table contains, for each element, the line-binned opacity as a function of the wavelength for the above-mentionned grid of conditions. The first column gives the wavelength at which the opacity is computed, and the following ones correspond to the line-binned opacities for the conditions (t,\rho,T) mentioned in the first three rows ; table_planck_opacity.txt is a table of Planck mean expansion opacities of all element for the above-mentionned grid of conditions. Each line gives, for a given element labeled by its atomic number Z in the first column, the Planck mean opacities for the conditions indicated in the first three rows.
