Caption: Figure 2.
Radial intensity profiles of 2P/Encke (red filled circles) compared with those of a standard star (black open circles), showing consistency with a point source in all filters. Note that the spatial profiles are consistent between the comet and the standard star across all filters, indicating that the observations were nearly diffraction-limited and any issues of varying seeing are negligible.
