The Fornax Cluster VLT Spectroscopic Survey II - Planetary Nebulae
  kinematics within 200 kpc of the cluster core
  We present the largest and most spatially extended planetary nebulae (PNe)
catalog ever obtained for the Fornax cluster. We measured velocities of 1452
PNe out to 200 kpc in the cluster core using a counter-dispersed slitless
spectroscopic technique with data from FORS2 on the VLT. With such extended
spatial coverage, we can study separately the stellar halos of some of the
cluster main galaxies and the intracluster light. In this second paper of the
Fornax Cluster VLT Spectroscopic Survey (FVSS), we identify and classify the
emission-line sources, describe the method to select PNe and calculate their
coordinates and velocities from the dispersed slitless images. From the PN 2D
velocity map we identify stellar streams that are possibly tracing the
gravitational interaction of NGC1399 with NGC1404 and NGC1387. We also present
the velocity dispersion profile out to $\sim 200$ kpc radii, which shows
signatures of a superposition of the bright central galaxy and the cluster
potential, with the latter clearly dominating the regions outside R $\sim
1000$" ($\sim 100$ kpc).
