Extragalactic PNe observed with 3D Spectroscopy

We describe our observations of extragalactic PNe using the technique of 3D spectroscopy (aka Integrated Field Spectroscopy). This method is particulary, and uniquely, suited to observations of sources where careful subtraction of the background emission is necessary. It is especially useful in the case where a PN emission line is coincident with a strong absorption or emission line feature of the background light from the underlying host galaxy, which would be difficult to estimate accurately enough with conventional slit spectroscopy. We describe our observations of some such PNe in various nearby galaxies, and the methods and results of our analysis. We then calculate the abundances using the ICF method for some of these PNe.
