Fig. 1.


Comparison between VLT/SPHERE/ZIMPOL deconvolved images of Psyche (top row) and the corresponding synthetic images generated by OASIS of our MPCD (second row) and ADAM (third row) shape models. The red arrows indicate the direction of the spin axis. Fourth and fifth rows: residuals in units of instrumental noise between the observed images and the synthetic images of the MPCD and ADAM shape models, respectively. Given that all images were taken close to opposition with a phase angle less than 9°, the color variation across the disk reflects a variation of albedo rather than a variation in topography. A map of the albedo variegation is shown in Fig. A.4.
