Abstract:
We present the first results of our search for new, extended planetary
nebulae (PNe) based on careful, systematic, visual scrutiny of the
imaging data from the Isaac Newton Telescope Photometric Halpha Survey
of the Northern Galactic plane (IPHAS).
The newly uncovered PNe will help to improve the census of this
important population of Galactic objects that serve as key windows
into the late-stage evolution of low- to intermediate-mass stars. They
will also facilitate study of the faint end of the ensemble Galactic
PN luminosity function. The sensitivity and coverage of IPHAS allows
PNe to be found in regions of greater extinction in the Galactic plane
and/or those PNe in a more advanced evolutionary state and at larger
distances compared to the general Galactic PN population. Using a set
of newly revised optical diagnostic diagrams in combination with
access to a powerful, new, multiwavelength imaging data base, we have
identified 159 true, likely and possible PNe for this first catalogue
release. The ability of IPHAS to unveil PNe at low Galactic latitudes
and towards the Galactic Anticentre, compared to previous surveys,
makes this survey an ideal tool to contribute to the improvement of
our knowledge of the whole Galactic PN population.
Description:
List and characteristics of 159 new true, likely and possible extended
PNe discovered in the framework of IPHAS. Also listed is the basic
information for the spectroscopic follow-up.

Note (1): Flags used by the MASH survey of Parker et al. (2006MNRAS.373...79P 2006MNRAS.373...79P,
V/127) to estimate the quality of the identification:
T = True. To indicate a spectroscopically and morphologically well defined
PN across perhaps several multi-wavelength images.
L = Likely. To indicate a not completely conclusive spectroscopic and/or
morphological identification though a PN ID is likely.
P = Possible. To indicate a non conclusive identification due to the
insufficient quality.
Note (2): The galactic coordinates of the object in the form lll.l+bb.b
where l and b stand for galactic longitude and latitude, respectively,
truncated to one decimal place (deg).
Note (3): Sexagesimal, equatorial position-based source name in the form
IPHASX JHHMMSS.S+DDMMSS for extended objects.
"J" indicates the position is J2000.
Note (4): Sexagesimal, equatorial coordinates. Center of the extended object.
Note (5): "--" stands for point source PNe
Note (6): "ERBIAS" and "amprs" morphological classifiers and sub-classifiers
respectively (see Parker et al. 2006MNRAS.373...79P 2006MNRAS.373...79P, Cat. V/127):
* First symbol (classifier):
E = Elliptical
R = Round
B = Bipolar
I = Irregular
A = Asymmetric
* other symbols (sub-classifiers):
S = quasi-Stellar (unresolved or barely resolved)
a = One sided enhancement/Asymmetries
m = Multiple shells or external structure
p = Point symmetry
r = Well defined Ring structure or annulus
s = Resolved, internal Structure
Note (7): Telescopes used for the spectroscopic follow-up as follows:
WH = WHT 4.2m
IN = INT 2.5m
SM = San Pedro Martir 2m
KP = KPNO 2m
GC = Grantecan 10m
OS = OSN 1.5m
MS = ANU 2.3m with DBS
WI = ANU 2.3m with WiFeS
SA: SAAO 1.9m
Note (8): Objects suggested as possible PN prior to IPHAS spectroscopic
confirmation and related articles.
