\tablefoot {The minimum value is estimated to be 0.5 in all cases.  If a range is given, the first number corresponds to 2000~K and the second the 8000~K temperature result.  For~example, if~the table lists 10$-$2, then the maximum fluctuation factor in the rate coefficient is estimated to be 10 near 2000~K and~2 near~8000~K.}
