The standard deviation of the yearly means from the mean of the means, the measure of long-term variability, is 0.0008 mag ( Table4 ), signi cantly larger than the precision with which we typically measure the yearly means. To search for photometric pulsations at the value of the inferred orbital period of the planet, the year-to-year photometric variation was removed by shifting the data from each season to the mean brightness of the rst observing season.... In PAGE 11: ... Zero phase is the time of mid-transit for favorable orbital inclinations. The semi-amplitude of a sine-curve t to the data with the period xed to the planetary orbital period is 0:00011 0:00009 mag ( Table4 ).

The individual observations in seasons 1, 2, 5, and 6 have been adjusted so that their yearly means equal those of seasons 3 and 4. Fourier analysis of these data at the planetary period gives a semi-amplitude of 0:00011 0:00009 mag ( Table4 ), so any real light variation at this period must be extremely small.

This is when the dark, unlit hemisphere of the planet faces the earth. The semi-amplitude results in Table4 show that we have achieved the highest precision for Boo, 1 Cnc, and CrB.

Using the transit probabilites in Table4 , computed as the ratios of the stellar radii to the semi-major axes of the planetary orbits (Schneider 1996), we calculate the probability of nding at least one transit from among the six planets that have negative transit-search results. This is given by P (one transit) = 1 ? P (no transits) (8) where P (no transits) is the probabability of nding no transits.... In PAGE 30: ... This is given by P (one transit) = 1 ?
