The longitudinal distribution of the equatorial SO2 column abundances. The perihelion data cover dates with a heliocentric distance of less than 5.04 AU and are normalized to perihelion. The aphelion data cover dates with a heliocentric distance of greater than 5.04 AU and are normalized to aphelion. In each case, the red line shows a cubic spline fit to the data points.
