|a SSV stands for Stanghellini et al. 2008, B&L for Bensby & Lundström (2001) and Ph02 for Phillips (2002). PNe from Ph02 are included in the sample sets (5-13) as additional, if they were not extracted by the SSV in their sample; d<1 denotes that a set of PNe have distances less than 1 kpc, , between 1 and 2 kpc, etc.; b the parameters of the fit ( and , respectively) and the correlation coefficient r are given for each sample. The number of PNe in the sample is given in the last column (N); - 3 PNe (He 1-5, HDW 6 and HaWe 5) are removed (see text).|
