ADC_Keywords: Nebulae, planetary ; Galaxies, nearby; Radial velocities Keywords: galaxies: elliptical and lenticular, cD - galaxies: kinematics and dynamics - instrumentation: spectrographs - planetary nebulae: general Abstract: We report on observations of four early-type galaxies performed with the Rutgers Fabry-Perot in order to search for planetary nebulae (PNe) in these systems. The aim is to use the PNe as kinematic tracers of the galaxy potential. We describe our data reduction and analysis procedure and show that the proper calibration of our detection statistic is crucial in getting down to our limiting magnitude of m5007=26.1. In the case of the two Leo galaxies, we find moderately sized samples: 54 PNe in NGC 3379 and 50 PNe in NGC 3384; NGC 4636 (two PNe) and NGC 1549 (six PNe) are included for completeness. We present our samples in tabular form, as well as the spectrum for each PN. Description: We observed the four galaxies in our sample with the Rutgers Fabry-Perot over the course of two runs at the Cerro Tololo Inter-American Observatory (CTIO) 4m Blanco telescope.

Note (1): E and W denote PNe found in the East and West fields, respectively. Nomenclature in Simbad: Table 5: [SW2006] NGC 3379 WNN Table 6: [SW2006] NGC 3384 WNN Note (2): Where the uncertainty in each coordinate is 0.4" (includes random and systematic uncertainty); Note (3): 5007mag=-2.5log(Flux)+13.74 (no extinction correction was made). Note (4): The spectra have a wide range in their number of data points and we determine Sc(α) for regions with one, two, or three pointings separately. Hence, the values of S listed in Table 6 are not always directly comparable.
