Query: The Frequency of Hot Jupiters in the Galaxy: Results from the SuperLupus
  Survey   We present the results of the SuperLupus Survey for transiting hot Jupiter
planets, which monitored a single Galactic disk field spanning 0.66 sq. deg for
108 nights over three years. Ten candidates were detected: one is a transiting
planet, two remain candidates, and seven have been subsequently identified as
false positives. We construct a new image quality metric, S_j, based on the
behaviour of 26,859 light curves, which allows us to discard poor images in an
objective and quantitative manner. Furthermore, in some cases we are able to
identify statistical false positives by analysing temporal correlations between
S_j and transit signatures. We use Monte Carlo simulations to measure our
detection efficiency by injecting artificial transits onto real light curves
and applying identical selection criteria as used in our survey. We find at 90%
confidence level that 0.10 (+0.27/-0.08)% of dwarf stars host a hot Jupiter
with a period of 1-10 days. Our results are consistent with other transit
surveys, but appear consistently lower than the hot Jupiter frequencies
reported from radial velocity surveys, a difference we attribute, at least in
part, to the difference in stellar populations probed. In light of our
determination of the frequency of hot Jupiters in Galactic field stars,
previous null results for transiting planets in open cluster and globular
cluster surveys no longer appear anomalously low.
