The [Particle Data Group _Review_](https://pdg.lbl.gov) uses asymmetric errors for many of its consensus particle data values (e.g. [quark masses](https://pdglive.lbl.gov/Particle.action?node=Q123)). These are in turn used by packages like [`Corpuscles.jl`](https://github.com/JuliaPhysics/Corpuscles.jl), which currently...
