Rotation period and total water production. The red line shows the observation, and the black lines the different sublimation models. Model A with globally constant surface active fraction (1∕12), model A/patches with best-fit adjustment of patches, and model P with effective sublimation curve and best-fit adjustment of patches. In all cases, the rotation period agrees reasonably well with observations. The total water production rate drops for model A and model A/patches scenarios with , while observations indicate .
