Area in synphot notebook

Description

In the section "Synthetic Photometry of a Simulated Source", when calculating the countrate for the specified observation, the area that is passed to the method is missing a factor because it is currently using the diameter of the telescope, instead of the radius. The area should be np.pi * (0.5*2.4 * u.m)**2). In this case, we could also use the stored parameter stsyn.conf.area.
