Reverse shock parameters as a function of attenuated RS velocity.

V _s	Log N(O)^a	n ₂	T ₂ ^b	v ₂	t _PIR

35	15.6	1.8 × 10⁴	182	194.4	0.33/120
70	16.6	2.2 × 10⁵	1500	31.8	1.98/723
100	17.0	5.4 × 10⁵	1500	18.5	3.4/1241
140	17.3	1 × 10⁶	1500	14.0	4.21/1537
200^c	17.0	1 × 10⁶	1500	20.0	3.17/1157

Notes. The pre-shock density n₀ and the PIR length L_PIR for all PIR models are 100 cm^-3 and 2 × 10¹¹ cm, respectively. Units – V_s: km s^-1; N(O): cm^-2; n₂: cm^-3; T₂: K; v₂: m s^-1; t_PIR: year/days.

^(a)

Values for the column density N(O) are taken from the shock models with conduction (70, 100, 140 km s^-1) and without conduction (35 km s^-1) of BS90 except for the 200 km s^-1 case.

^(b)

The T value for the 35 km s^-1 shock is from BS90, while other values are derived from DS10.

^(c)

Values for this model are derived from DS10 except for the UV flux taken from BS90 for the RS velocity 170 km s^-1.
