ATPM derived properties of 67P/C-G using the Kelley et al. (2009) and Lamy et al. (2008) data sets at the 3-σ confidence level.

Data set	Kelley et al. (2009)	Lamy et al. (2008)

Effective radius (km)	1.97 ± 0.04	2.01 ± 0.05
P_R albedo	0.060 ± 0.005	0.058 ± 0.005
Thermal inertia (J m^-2 K^-1 s^−1/2)	<15 (4 mean)	4 assumed
Roughness fraction	>0.65 (0.9 mean)	0.7 ± 0.2

Notes. The values quoted are either the range of possible parameters or the mean and standard deviation of the 3-σ distributions shown in Figs. 10 and 11.
