Abstract:
We present new planetary nebulae (PNe) positions, radial velocities
and magnitudes for six early-type galaxies obtained with the Planetary
Nebulae Spectrograph (PNS), along with derived two-dimensional
velocity and velocity dispersion fields, and the α parameters
(i.e. the number of PNe per unit luminosity). We also present new deep
absorption-line long-slit kinematics for three galaxies in the sample,
obtained with the FOcal Reducer and low dispersion Spectrograph
(FORS2) at the Very Large Telescope (VLT).
