Wosret spectrophotometry. Top: examples of blue patches and bright spots from 13 June 2016 (left) and 2 July 2016 images (right). Inserts show a zoom of some ROIs. Middle and bottom panels: corresponding relative reflectance and the I over F value at the given phase angle (70° and 93° for the June and July images, respectively). The dark terrain used in the mixing model is represented by a circle in white for clarity in the RGB images on the top and in black in the plots.
