The points (filled circles) and dashed line represent the raw measurements obtained by integrating within the eight homothetic ellipses defined in the text. The open circles and solid line represent the measurements corrected for the local sky-background calculated from the two largest ellipses. The error bars are obtained from the standard deviation of the curve of growth.
