i. Examples of Radial Profile Fitting

Below are some examples of the radial profile fitting technique. The layout for all the image figures is as follows:

The color code for the elliptical contours shown on the image figures is as follows:

The color code for the corresponding Ks-band surface brightness profiles is as follows:

Object 1, J = 11.85, H = 11.32, Ks = 11.04 mag.
