Notes. Rotational cross sections of OCS for collision with para-H₂ using one (j_H₂ = 0) and two (j_H₂ = 0, 2) rotational states of H₂ in the basis for the close-coupling calculations at selected transitions. The cross sections for the collision with ortho-H₂(j = 1) as well as those for the collision with He from Denis-Alpizar et al. (2023) are also included.
