Abstract:
We present [OIII]λ5007 fluxes and angular diametres for 435
Planetary Nebulae (PNe) in the central 10°x10° region towards
the Galactic bulge. Our sample is taken from the new discoveries of
the MASH PN surveys as well as previously known PN. This sample
accounts for 80 per cent of known PN in this region. Fluxes and
diametres are measured from narrow-band imaging with the MOSAIC-II
camera on the 4-m Blanco Telescope at the Cerro-Tololo Inter-American
Observatory. This is the largest (∼60deg2), uniform
[OIII]λ5007 survey of the inner Galactic bulge ever undertaken.
104 of the objects have measured [OIII]λ5007,
[OIII]λ4959, Hα or Hβ fluxes from the literature,
which we use to undertake a detailed comparison to demonstrate the
integrity of our new fluxes. Our independent measurements are in
excellent agreement with the very best literature sources over two
orders of magnitude, while maintaining good consistency over five
orders of magnitude. The excellent resolution and sensitivity of our
data allows not only for a robust set of homogenous PN fluxes, but
provides greater detail into their intricate, otherwise undetermined
[OIII]λ5007 morphologies. These new, extensive measurements
significantly increase the sample of reliable [OIII]λ5007
fluxes for Galactic bulge PN making it a valuable resource and a
prelude to the construction of our new Galactic bulge PN luminosity
function (Paper II, Kovacevic et al., in prep.).
Description:
We observed previously known and MASH PN in a 10°x10° region
towards the Galactic bulge using the Cerro-Tololo Inter-American
Observatory (CTIO) 4-m Blanco Telescope in Chile with the MOSAIC-II
CCD Imager. A total of ∼95h of photometric imaging was conducted,
spread over two observing runs: six nights throughout 2008 June 9-14
and five nights from 2009 June 27 to July 2.
