Abstract:
More than 1500 Galactic planetary nebulae (PNe) are known but only a
tiny fraction of them have measured proper motions. To date, the
largest set of proper motion (PM) data for PNe is the one by Cudworth
(1974AJ.....79.1384C 1974AJ.....79.1384C), which includes 62 objects 25 of which have PM
with significance better than 3σ.
With our new compilation of 234 PNe we enlarge - compared to
Cudworth's 25 - by almost an order of magnitude the number of PNe and
central stars (CSs) with reliably measured proper motion (i.e. with
significance better than 3σ in at least one component) and
confirm some previous measurements.
We have used all-sky astrometric catalogues available via the Vizier
database to collect proper motion information for a sample of objects
selected from the catalogue of PNe positions of Kerber et al. (2003,
Cat. J/A+A/408/1029).
Description:
Master proper motion catalogue. The columns give: the PNG number and a
common name, the PN morphological classification according to Kerber
et al. (2003, Cat. J/A+A/408/1029), the pro per motions in Right
Ascension ({muα) and Declination (µδ) in mas/yr
together with their associated errors according to the Hipparcos,
Tycho-2, UCAC-2, USNO-B and GSC-II catalogues, the proper motion
grading defined in section 2.3. Note that the PM value s from USNO-B
are not absolute but relative to the YS4.0 catalog. Hence they cannot
be directly compared with the other columns.

140 A1 --- Type [ABCD] Significance of proper motion (1)
--------------------------------------------------------------------------------
Note (1): Types as follows:
A = proper-motion at ≥5σ in at least one component, confirmed
by at least one other independant catalogue (≥3{sigma)
B = proper-motion at 3≤σ≤5 in at least one component,
confirmed by at least one other independant catalogue
C = proper-motion at ≥3σ in at least one component, in one
catalogue only
D = proper-motion at ≥3σ in at least one component, but
discrepancies with other catalogues or a large error bar
(≥30mas) make the significance questionable
Note (2): Classes defined as follows (from J/A+A/408/1029):
CS = A central star is known or recognizable, clearly separated
from the nebula.
ST = The nebular itself is stellar like or unresolved
PH = The nebula is either resolved or extended with a well defined
photometric center.
GEO = The nebula is extended either ring-like or symmetric in general,
or with a more complex morphology and no well defined
photometric center.
