(a) Histograms of engine-intake minus canvas bucket SST measurement differences for each of two 1924 West Indies cruises of the R.M.S. Empress of Britain: (blue bars), 18 January–20 February 1924, N = 113, µ= 0.76 °C, σ = ±1.6 °C; and (red bars), 23 February–23 March 1924, N = 101, µ = 0.79 °C, σ = ±1.7 °C. The red bars have been narrowed to improve visualization. (b) (points), combined bucket minus intake differences from the same two West Indies cruises; (red line), Lorentzian fit (Γ = 1.53, x₀ = 0.55, r² = 0.95).
