## Description

Description of supplementary material for : Ab initio calculations of collisional line–shape parameters and generalized spectroscopic cross-sections for rovibrational dipole lines in HD perturbed by He by Kamil Stankiewicz, Hubert Jóźwiak, Maciej Gancewski, Nikodem Stolarczyk, Franck Thibault, Piotr Wcisło The generalized spectroscopic cross-sections as a function of collision relative kinetic energy defined by Eq.4 are given in files HD_HeXS*.txt. The values in subsequent columns are the kinetic energy, the real part of σ0q (PBXS), the imaginary part of σ0q (PSXS), the real part of σ1q (RDXS), the imaginary part of σ1q (IDXS) and the inelastic contribution to the PBXS (Inel. Contr.). Kinetic energy is given in cm-1, the cross-sections and inelastic contribution in Å2. For example the file HD_HeXS2_0R_4.txt provides the cross-sections for the electric dipole R(4) line of the 2-0 band. The thermally averaged pressure broadening and shift coefficients (PBC and PSC), real and imaginary parts of the optical frequencies of velocity-changing collisions (Re(νopt) and Im(νopt)), defined by Eqs. 6 and 7, are given in the HD_Heline_shape*.txt files. Temperature is given in K and the values of the coefficients in 10-3 cm-1/atm. For example file HD_Heline_shape5_0P_3.txt contains data for electric dipole P(3) line of 5-0 band.
