Water production rates of comet 67P measured during earlier apparitions near perihelion. Models A and D for a homogeneous nucleus are scaled to the observed maximum. Model E is a best fit for spotted activity. Model F is calculated for the same distribution but with a thermal inertia of 100 [J m-2 K-1 s−1/2].
