R-band surface brightness profiles, derived separately for the northern (up-triangles) and southern (down-triangles) sides and for the entire galaxy (dots). The profiles are not corrected for internal extinction and inclination. The red-dotted line shows an exponential fit to the southern profile, giving μ0 = 22.0 mag arcsec-2 (~40 L⊙ pc-2) and R0 = 13.1′′ ± 0.1′′ (~203 pc).
