Notes. The number N of sources participating in the median for each transition is listed in Col. 2. When only one source is available, we use the actual ratio and the uncertainty computed with standard error propagation, when only two sources are available we use the weighted average. The median absolute deviation of a sample of values x is defined as m.a.d.(x) = median(|x−median(x)|). The 5th, 6th and 7th columns report the same L′ ratios derived from the Tables in Carilli & Walter (2013, CW13), Boogaard et al. (2020, B20), and Harrington et al. (2021, H21).
