Fig. 1From: Geometric correction for thermographic images of asteroid 162173 Ryugu by TIR (thermal infrared imager) onboard Hayabusa2Schematic view of Ryugu coordinate and TIR and Hayabusa2 frames relation. The TIR frame is rotated in the Euler angle of \(\theta _y = -180^\circ\) relative to the Hayabusa2 frame. Rays from a polygon of a Ryugu shape model are incident to TIRBack to article page
