Color profiles of 108 UDGs identified in HFF fields

<p>Multi-band surface brightness profiles of&nbsp; 108 UDGs identified in HFF fields. Details about each diagram are listed below.<br> Panels\,(1) to (3) show the F814W band cutout-images of the UDG, the best-fitting GALFIT model and residual image. The bar at top-right of panel\,(2) represents 1.5\,kpc assuming the cluster redshift.<br> Panels\,(4) to (6) show PSF-matched images in F606W, F814W and F160W bands.<br> In panels\,(7) to (9), we mask neighboring sources classified by `Noisechisel&#39; and overplot our elliptical annuli used in surface brightness analysis.<br> Panel\,(10) presents three-band surface brightness profiles of each UDG,<br> x-axis of colorful points correspond to the out-radius of elliptical annuli.<br> In panel\,(11), we convert observed color profiles into rest-frame U\,-\,V and V\,-\,I profiles.<br> F814W and F160W surface brightness profiles in panel\,(10) and rest-frame V\,-\,I profiles in panel\,(11) are shifted a bit to the right.<br> Finally, the colors of the UDG from inside to outside are shown in the UVI diagram in panel\,(12).<br> Please note that for UDGs which do not have F160W observations will not have panels (6),(9),(12).</p>
