Distance estimates with globular clusters

Before we begin, I encourage anyone not familiar with filters or the magnitude system to read the background. It is also assumed that you have a plotting program such as Excel or OpenOffice and know how to use it. You can download Open Office Suite and read the short tutorials. When you are ready, please proceed ahead to create an H-R (Hertzsprung-Russell) diagram.
