Fig. A.3


Logarithmic surface brightness profile (in photon counts) of the HST F606W image used for the dust-masking. Every dot is a pixel in the image, the lower envelope fit of the surface brightness is given by the red solid line. Each pixel below the line is masked in the photometric measurement of the MGE. The green dashed line marks the edge of the image which is used for the MGE modeling.
