Demonstration of BF calculation for NGC 2632. (Top row) Absolute CMDs for leading tail, cluster, and trailing tail. (Middle row) Absolute CMD for all stars coloured according to the mass ratio (q). The isochrone (dotted grey curve) and main-sequence ridge line (dashed red curve) are shown for reference. (Bottom row) The MF of the visible members of the cluster and tidal tail. Kroupa (2001) IMF is shown for reference. The lower limit of credible mass estimates is indicated by the grey-shaded region.
