Fig. 5

Surface brightness profiles for the comet in a) August; b) September; c) October; d) November 2007; and e) March 2008. The points show the comet profile, while the line shows the image PSF. a)–c) show star-like profiles, while e) shows clear activity. d) is difficult to interpret due to residuals in the image from saturated stars (the bumps beyond ρ = 1″). The gaps in the comet profiles in a)–c) around ρ ~ 2″ are due to the negative imprint from the reference image.
