Abstract:
We present results from Planetary Nebula Spectrograph (PN.S)
observations of the elliptical galaxy NGC 3379 and a description of
the data reduction pipeline. We detected 214 planetary nebulae, of
which 191 are ascribed to NGC 3379 and 23 to the companion galaxy
NGC 3384.

Note (1): PNS-EPN NGC3379 NNN in Simbad. The PN.S data follow the usual
definitions, and the ID is chosen to be compatible with proposed IAU
standards (EPN standing for "Extragalactic Planetary Nebula").
Note (2): Objects were considered matched with a PN in our catalog if the
positions agreed within 3.0arcsec and their velocities within 100km/s
without adjustment for systematic offsets in either case. Objects with
an ID starting with "6" are taken from table 6 of Sluis et al. (2006,
J/AJ/131/2089).
