That's true. So we have to check the distance.
HazCam Right B is fixed to the rover, so comparing the y-pixel position of the two targets in respective Hazcam images should give a good comparison of the respective rover position to the target, as long as the x-position is near the center, plane ground assumed in both cases. The following gif based on the Hazcam images for Sol 234 and Sol 280 helps to compare the two y-pixel positions: Link to the gif. The y-pos of the targets is almost the same to my eyes. Cited from this ChemCam paper: QUOTE The Mast Unit (Figure 8) focuses on a target, generates a series of laser pulses, and collects light for the LIBS analysis. It also takes images with the RMI. It is mounted atop the MSL mast to benefit from the mast’s pointing capability. Hence, to get the same pointing of the RMI the mast position relative to the rover, and therefore the distance to the target should be roughly the same for both ChemCam images. This was to check. |
