Table 3:

Summary of the sets of state-to-state rate coefficients (STSR) available in BASECOL (sets (1), (2), (3), (4) below 10th level), and effective rate coefficients (ER) .

Set				(K)	(K)	Transitions	T1	T2
(1)	j2 = 1	j'2 = 1	STSR	5	1500	20 levels	5%	10%
(2a)		j'2 = 3	STSR	300	1500	20 levels	20%	20%-40% (Note)
(2b)		j'2 = 3	STSR	5	300	20 levels	A2	A2
			ER	5	1500	20 levels	5%	15%-20%
(3)	j2 = 3	j'2 = 1	STSR	5	1500	10 levels	A2
(4)		j'2 = 3	STSR	5	1500	10 levels	10%
			ER	5	1500	10 levels	15%

Notes. Column 1 labels the set of state-to-state rate coefficients. (K) and (K) indicate the lowest and highest temperatures at which calculations and fits have been performed for the relevant sets of data. The column ``Transition'' indicates the number of levels among which rate coefficients are provided. T1, T2 indicate the worst expected accuracy: T1 for transitions among the 10 first levels of para-H<sub>2</sub>O, T2 for de-excitation from the 11th-20th levels. A2 means ``not good but negligible''. Note: for set (2a) and T2, the accuracy is 20% for de-excitation to the first 13th levels and 40% for de-excitation to the 14th-19th levels.
