Using Monte Carlo simulations we analyze the potential of
the upcoming transit survey Pan-Planets. The analysis covers the
simulation of realistic light curves (including the effects of
ingress/egress and limb-darkening) with both correlated and
uncorrelated noise as well as the application of a
box-fitting-least-squares detection algorithm. In this work we show
how simulations can be a powerful tool in defining and optimizing
the survey strategy of a transiting planet survey. We find the
Pan-Planets project to be competitive with all other existing and
planned transit surveys with the main power being the large 7 square
degree field of view. In the first year we expect to find up to 25
Jupiter-sized planets with periods below 5 days around stars
brighter than V = 16.5 mag. The survey will also be sensitive to
planets with longer periods and planets with smaller radii. After
the second year of the survey, we expect to find up to 9 Warm
Jupiters with periods between 5 and 9 days and 7 Very Hot Saturns
around stars brighter than mag as well as 9 Very Hot
Neptunes with periods from 1 to 3 days around stars brighter than
mag.
