Panel a: ternary plot of the probabilistic fractions f_i with f_{M 105, Ser} > 0.5 coloured in orange, f_{M 105, Exp} > 0.5 coloured in purple, and f_NGC 3384 > 0.5 represented by crosses on a red-to-blue colour scale with red colours for f_{NGC 3384, bulge} > 0.5 and blue colours for f_{NGC 3384, disk} > 0.5. Points coloured in grey do not satisfy any of the four criteria, and their association with any of the components cannot be conclusively ascertained. Panel b: spatial distribution of PNe with the same colour coding as in panel a. Panel c: velocity phase-space along the major axis of M 105 with the same colour coding as in panel a. Panel d: velocity phase-space along the minor axis of M 105 with the same colour coding as in panel a.
