Radial numerical density profiles fitted by King profiles. The empty grey circles and filled black diamonds are the observed profiles, original and corrected by completeness (Fig. 2), respectively. Solid lines are King profiles fitted to the data points. The horizontal and vertical dashed grey lines are n_field and r_c, respectively, for the original profile, the dash dotted black lines for the corrected profile. HW34 does not present a high enough density contrast to be fitted by a King profile.
