| a Notes: The table lists the comet component (SW3 Comp), the structure designation (ID), the near-nucleus position angle (PA; measured North over East), the curvature (Curv), and minimum extension (MinExt), plus some comments. In columns ``PA'', ``Curv'', ``MinExt'' the measurements for the four observing nights are listed, separated by ``/''. Abbreviations: nd = not detected, CC = counterclockwise, S = straight. The various coma structures are identified in Figs. 8 and 9. |
