Abstract
In this paper, we present the first extended catalogue of far-infrared fluxes
of Galactic bubbles. Fluxes were estimated for 1814 bubbles, defined here as
the `golden sample', and were selected from the Milky Way Project First Data
Release (Simpson et al.) The golden sample was comprised of bubbles identified
within the Wide-field Infrared Survey Explorer (WISE) dataset (using 12- and
22-$\mu$m images) and Herschel data (using 70-, 160-, 250-, 350- and 500-$\mu$m
wavelength images). Flux estimation was achieved initially via classical
aperture photometry and then by an alternative image analysis algorithm that
used active contours. The accuracy of the two methods was tested by comparing
the estimated fluxes for a sample of bubbles, made up of 126 H II regions and
43 planetary nebulae, which were identified by Anderson et al. The results of
this paper demonstrate that a good agreement between the two was found. This is
by far the largest and most homogeneous catalogue of infrared fluxes measured
for Galactic bubbles and it is a step towards the fully automated analysis of
astronomical datasets.
