Logarithmic surface gravity versus effective temperature diagram showing the location of GLMP 334 and IRAS 15482 − 5741 (red filled triangle) and previously identified post-AGB objects (black filled squares). Data from post-AGB stars were taken from Luck (1993), Reddy et al. (1999, 2002), Reyniers et al. (2004), and van Winckel & Reyniers (2000). HD 172481 (Reyniers & van Winckel 2001) is also shown (red filled square). Post-AGB tracks of Schönberner (1983) and Blöcker & Schönberner (1990) are also shown.
