Top: simulated views of Steins obtained at the beginning (left) and at the end (right) of VIRTIS-M observations, i.e., between 18:38:19 and 18:39:22 UTC approximately. The phase angle significantly changed during the observations (see text). In color: simulated thermal maps of Steins for three different thermal inertias (from top to bottom Γ = 10 − 100 − 300   J   m^-2   K^-1   s ^− 1/2). Surface temperature is color-coded according to the scale on the color bars. The VIRTIS footprints, not represented here, were located on the right side of each image (see Fig. 10).
