Table 1: Details of the quantum MOLSCAT cross section calculation parameters. $J_{1\rm up}({\rm HC_3N}) \leq 15$ (10 for He). Methods: CC, Close coupling, CS, Coupled states approx., IOS, Infinite Order Sudden approx.
Table 2: ${\rm HC_3N}$ -para- ${\rm H_2}$ (J=0) collisions. Quantum deexcitation rates in ${\rm cm^3~s^{-1}}$ , for J₁'=0, for successive initial J₁ and for various temperatures. Powers of ten are denoted in parentheses.
Table 3: ${\rm HC_3N}$ -para- ${\rm H_2}$ collisions. Quantum or QCT ( $^\dag$ ) deexcitation rates in ${\rm cm^3~s^{-1}}$ , for J₁-J'₁=1,2,3,4, for various temperatures and representative values of J₁. Powers of ten are denoted in parentheses.
Table A.1: Fitting coefficients of HC₃N-para-H₂(J₂ = 0) rates, following formula (5). J₁ and J'₁ are the initial and final rotation states, respectively. The rates thus obtained are in ${\rm cm^3~s^{-1}}$ . Rates are quantum for $J_{1 \rm up} \protect\le 15$ , classical otherwise.
