Dataset for "Collisional Excitation of CaO and CaS by Helium: Cross Sections, Rate Coefficients and Line Ratio Diagnostics"

This archive contains complete numerical data supporting the paper "Collisional Excitation of CaO and CaS by Helium: Cross Sections, Rate Coefficients and Line Ratio Diagnostics" (#AAS76886). The data comprises: (1) ab initio potential energy surface data points for the CaO–He and CaS–He systems; (2) radial coefficients of the Legendre expansion of the rigid rotor potential; (3) rotationally (de)excited state-to-state cross sections induced by He collisions; (4) corresponding rate coefficients as a function of temperature (5–150 K); (5) output files from the non-LTE radiative transfer simulation (RADEX), including excitation temperatures, brightness temperatures, optical depths, and line ratio diagnostic grids for four observed CaO transitions (4→3, 5→4, 9→8, and 10→9). All figures in the paper are based on these data. Detailed descriptions of each file can be found in the readme.txt file within this archive.
