Metallicity
The interpretation of data is often the hardest and most
interesting aspect of science. It is often a long and involved process
requiring many people from many fields to work together in order to
understand what a given set of data really means. However in our case
we are only looking for a basic statement about metalicity within our
galaxy. In order to answer that ask youself
these questions:
What does this data tell you about the Milky Way?
How can we use what we have in order to construct a map of the galaxy?
Once you feel you have a pretty good idea, or no idea what so
ever, feel free to read about what this information can tell us about
the galaxy we live in.
