Extended Data Fig. 3: Estimation of the thermal inertia of hotspots.
From: Anomalously porous boulders on (162173) Ryugu as primordial materials from its parent body
a, Comparison of simulated temperature averaged in the ID126 crater with variable thermal inertia (black line) and observed temperature for the hotspot (red horizontal line). The error bars show the standard deviation within the relevant pixels. By comparing the observed HS1 temperature with the simulated average temperatures in the ID126 crater, the best-fit TI value is 73 tiu for the hotspot. b, Simulated temperature image around ID126 crater (dashed circle) with TI = 200 tiu. The position of HS1 is indicated as red point. c, Similar to a but for hotspot HS2. The simulated data are the average of the hotspot (red-filled circle) in the simulated image of d.
