^a Heliocentric distance (AU) of observation. ^b Linear radius of the reference aperture at the comet. The symbol $\S$ corresponds to values by Meech et al. (2009) computed all using a 3.0 $^{\prime\prime}$ radius photometric aperture. ^c Integrated R magnitude in the reference aperture. $^\dagger$ Indicates a value obtained as the mean of the given light curve. # Indicates the average reduced R magnitude for $r = \Delta = 1$ and $\alpha = 0^{\circ}$ . ^d $^\ddagger$ Indicates that the value is not given by the respective authors in the reference, but it has been computed for this paper with their data by means of Eq. (2) (see text). ^e Derived from a theoretical model.
