Abstract:
We present a catalog of 535 planetary nebulae (PNs) discovered in the
flattened elliptical galaxy NGC 4697, using the FORS1 Cassegrain
spectrograph of the Very Large Telescope of the European Southern
Observatory at Cerro Paranal, Chile. The catalog provides positions
[(x,y)-coordinates relative to the center of light of NGC 4697, as
well as α,δ] and, for almost all PNs, the magnitude
m(5007) and the heliocentric radial velocity in km/s.
Description:
The observations and scientific results have been described in Mendez
et al. (2001ApJ...563..135M 2001ApJ...563..135M, Paper I).

Note (1): Notes as follows:
1 = emission-line region within an extended source (galaxy)
2 = point source in on-band and grism+on-band, visible but
not stronger in off-band
3 = point source in on-band, stronger in off-band, absent in grism+on-band
4 = point source in on-band and grism+on-band, not visible in off-band, but
wrong velocity for NGC 4697 if identified as [OIII]λ5007
5 = point source in on-band, visible but weaker in off-band, absent in
grism+on-band, variable star(?)
