Searching for Life Outside Our Solar System

For this assignment you are going to practice some of the data analysis that astronomers have to do to look for evidence of extrasolar planets. You are given six example graphs of data that use three different methods: the astrometry method the wobble or spectral method and the transit method.
I have provided some notes in the reading section on each of these methods using the same types of diagrams I provide for the assignment. You will also be able to find a lot online about these methods and the discoveries made with them.
There are two examples for each of three methods: Astrometry Spectral and Transit methods.
For each example you are to determine if there is sufficient evidence to claim that there is an extrasolar planet orbiting the star. You are going to do this six times once for each of the graphs. They are not connected to each other.
