Images in the five UVIS filters and the Hα emission map for two target galaxies. Images were smoothed and convolved with a Gaussian kernel to reduce the noise on small spatial scales and to highlight large-scale background variations. The white contours are isophotes from the F606W image shown to visualize the stellar sources as a reference. The black squares show the 12 regions that were used to evaluate the statistical properties of the images.
