Bar properties and photometry of barred low surface brightness disc
  galaxies
  We measure the bar properties (length, strength, and corotation radius) of a
sample of barred low surface brightness (LSBs) galaxies and compare to previous
results for both LSBs and high surface brightness galaxy (HSBs) samples. In
addition, we present new optical $\textit{B}$- and $\textit{I}$-band surface
brightness profiles, magnitudes, and colours. We find that bars in LSBs are
shorter and weaker when compared with those in HSBs galaxies. Based on analysis
of four different bar length measures on simulated galaxy images, we find our
bar length measure based on azimuthal light profiles is the most accurate out
of the four tested here when seeing effects are taken into account. We also
find that bars in LSBs have comparable relative bar pattern speeds to those in
HSBs, the majority of which we find to be `fast' (i.e. $\mathcal{R} <$ 1.4). In
general, we find that our barred LSBs have comparable central surface
brightnesses and total magnitudes to unbarred LSBs, albeit slightly brighter.
Our barred LSBs fall on a shallower disc scale length (h) vs $M_{B}^{T}$
relation than unbarred LSBs. Finally, we find our barred LSBs to be just as gas
rich as unbarred LSBs (i.e. $M_{gas}/(M_{gas} + M_{*}) > 0.5$).
