a statistical fluctuation. We will need to compare the performance of this
rank statistic algorithm against that of other photometric algorithms. With
color information from other surveys available, we will be able to estimate
the distribution of target stars in a given field as a function of angular
size. Currently, 500-720 nm band-pass filters are used for all telescopes. It
is possible that we could obtain color information by using different filters.
By considering the real spectrum of a distant star, it is also likely that
we can have some calibration method for our system. Small comets are
believed to be non-spherical in general. How a result derived from a spher-
ical model can be extrapolated for a more general case is not clear at this
time. Space-based experiments were proposed

for COROT and Kepler
missions. The velocity of a satellite (typically, 7-8 km/s in some direction
along its orbit) will contribute to the shadow speed in the shadow level.
This alone might change the occultation event rate, which is proportional
to the shadow speed, by 20-30%.
