UM422. Left panel: surface brightness and color radial profiles for elliptical (open circles) and isophotal (red circles) integration in the Vega photometric system. Upper right panel: contour plot based on the B band. Isophotes fainter than 23.0, 25.5 are iteratively smoothed with a boxcar median filter of sizes 5, 15 pixels respectively. Lower right panel: a true color RGB composite image using the U,B,I filters. Each channel has been corrected for Galactic extinction following Schlegel et al. (1998) and converted to the AB photometric system. The RGB composite was created by adapting the Lupton et al. (2004) algorithm.
