A Large Scale, Low Frequency Murchison Widefield Array Survey of
  Galactic HII regions between 260< l <\340
  We have compiled a catalogue of HII regions detected with the Murchison
Widefield Array (MWA) between 72 and 231MHz. The multiple frequency bands
provided by the MWA allow us identify the characteristic spectrum generated by
the thermal Bremsstrahlung process in HII regions. We detect 302 HII regions
between 260 < l < 340 and report on the positions, sizes, peak, integrated flux
density, and spectral indices of these HII regions. By identifying the point at
which HII regions transition from the optically thin to thick regime we derive
the physical properties including the electron density, ionised gas mass and
ionising photon flux, towards 61 HII regions. This catalogue of HII regions
represents the most extensive and uniform low frequency survey of HII regions
in the Galaxy to date.
