Cloudiness distributions during simulated voyages using calcite sunstones at summer solstice with navigation periodicity Δ t = 1 hour for cloudiness dominances m dominance = -1, 0 or 1 (meaning dominantly weakly, medium or strongly cloudy skies) and for cloudiness changeabilities σ changeability = 1, 2 or 4 (meaning weakly/slowly, medium or strongly/rapidly changing cloudiness).
