Fig. 3
Surface brightness profile of a BCD (VCC 0001). Left panel: the line corresponds to an exponential fit to the LSB-component and the red data points show the outer tail in the r-band. Right panel: same, but for the g, r and i-filters. Obvious are the outer tails of the profiles at low surface brightness levels. The horizontal bars indicate the radius at which the profile starts deviating from a pure exponential fit.
