Influence of individual photometric parameters on the phase curves. The asterisk in the legend denotes the best-fit solution retrieved for the Sol 32 R band. Panels (a–e) show simulations in which only one parameter is varied at a time while all other parameters are fixed at their best-fit values. The vertical dashed line indicates the maximum observed phase angle for Sol 32; phase angles to the left correspond to the measured range, whereas those to the right represent the extrapolated range.
