Q:  How deep is that dip in brightness?  In other words, what fraction
           of the star's disk was covered?


        The star's brightness decreases from 1.0 units of flux to 
        about 0.985 units of flux.  That means that

               0.015         of the star's light was blocked
         or
               1.5 percent   of the star's light was blocked


   Q:  If that star is like our Sun, how large is the planet?


             (area of planet)
             ----------------             =    0.015
             (area of star)   


              pi * (planet radius)^2
             ------------------------     =    0.015
              pi * (star radius)^2


                   planet_radius     =   sqrt(0.015) * star_radius


        Now, if the star is identical to our Sun, it has a radius
        of 6.96 x 10^(8) meters.  In that case, 


                   planet_radius     =    0.122 * 6.96 x 10^(8) meters

                                     =    8.5 x 10^(7) m

                                     =    85,000 km

        which is larger than Jupiter.
