A one-parameter family of trans-series asymptotics as τ → ±∞ and τ → ±i∞ for solutions of the degenerate Painlevé III equation (DP3E), ′′(τ) = (′(τ))²/(τ) − ′(τ)/τ + 1/τ(−8ε(u(τ))² + 2) + ²/(τ), where ε ∈ {±1}, ∈ ℂ, and ∈ ℝ∖{0}, are parametrised in terms of the monodromy data of an associated firs...
