Using formula from §5: [ t_j \approx 1.2 \times \left(\frac10^5310^53\right)^1/3 \times 1 \times \left(\frac0.050.1\right)^8/3 ] [ t_j \approx 1.2 \times (0.5)^8/3 ] [ (0.5)^2.666 \approx 0.157 \quad \Rightarrow \quad t_j \approx 0.19 \ \textdays \ (\approx 4.5 \ \texthours) ] grb physics for competitions vol 2 pdf best
