Open Access

Table 2

Time taken (s) for differing methods and intensity thresholds (cm molecule⁻¹) to compute opacities using the 500 million transitions of the BT2 water line list (Barber et al. 2006) between 0 and 30 000 cm⁻¹ with a wavenumber binning of 0.1 cm⁻¹.

Method	Threshold	Time(s)
Vec-Voigt	0	251.2
Humlíček	0	2775.6
Vec-Voigt	10⁻³⁰	70.0
Humlíček	10⁻³⁰	832.6

Notes. I/O time is not considered. Test was performed on single core on an Intel Core i5-2500 CPU at 3.30 GHz with 16 GB RAM.
