Position of the exciting star of PN G342.0-01.7 is marked as a red circle as derived from photoionisation modelling compared with evolutionary tracks of central stars of PNe from Vassiliadis & Wood (1993). The grey area represents the error ellipse defined by the uncertainties in the flux and distance estimates, and by the uncertainties in the theoretical modelling. Note that the tracks are marked in terms of the initial stellar mass, rather than of the remnant core.
