Table 4

Summary of the thermal inertia results for the different physical models of Kamo‘oalewa.

Model	Peak 1	Peak 2	Peak 3	Best estimate	P(Γ < 1000)
1	46	138	2456	$147_{- 40}^{+ 77}$ $147_{ - 40}^{ + 77}$	0.97
2	41	145	/	$152_{- 42}^{+ 74}$ $152_{ - 42}^{ + 74}$	0.99
3	43	136	2947	$148_{- 41}^{+ 77}$ $148_{ - 41}^{ + 77}$	0.91
4	31	177	/	$181_{- 59}^{+ 95}$ $181_{ - 59}^{ + 95}$	0.99

Notes. The nominal values of the peaks are reported in columns 2, 3, and 4. The best estimate for Γ is reported in column 5. All the values are reported with usual thermal inertia units of J m⁻² K⁻¹ s^−1/2. Column 6 shows the probability that Γ is smaller than 1000 J m⁻² K⁻¹ s^−1/2.
