Notes. Column 1–4 labels the involved ionic or covalent asymptotic states, where the indices correspond to the states listed in Table 3. Columns5–6 and 8–9 list rate coefficients for various processes defined by the subheadings, and Cols. 7 and 10 labeled δBV17 give the quotient of the rates from this work with the results from BV17. Only channels involving at least one rate coefficient larger than 10−9 cm3 s−1 in either this work or BV17 are included. All numbers are rounded off to two significant digits, and square brackets denote powers of ten (i.e., [X]≡10X).
