Temperature as a function of cometary depth for the orbital position corresponding to early August 2015. Model C slow and fast rotator cases are studied for two primordial core temperatures, 20 K and 30 K. The curves (solid and dashed) starting at higher surface temperature correspond to a slow rotator. The MIRO mean upper value of thermal inertia of 30 J m^-2 K^-1 s^0.5 is used (Schloerb et al. 2015).
