Two data files are provided, both with energy levels, transition frequencies and Einstein A coefficients from CDMS (version of July 2005) and collisional rates from Balança et al (2016). The file for low temperatures (<50 K) contains full quantum calculations (CS approximation) for SO₂-H₂ collisions at temperatures in the range from 5 to 50 K including energy levels up to 38 cm^-1.

For higher temperatures, the second datafile provides quasi-classical calculations (IOS approximation) for SO₂-H₂ collisions at temperatures up to 720 K including energy levels up to 517 cm^-1.
