In SkyServer projects or in your own studies, you will often need to make graphs or calculations with data. SkyServer can’t directly analyze data, so you will need to use a graphing program.
In this brief how-to tutorial, you will learn many of the skills required to make graphs and calculations with SkyServer data. The tutorial uses Excel, a spreadsheet program published by Microsoft. We chose to use Excel because it is a commonly used, relatively simple program that can graph and analyze many different types of data.
If you use a plotting program other than Excel, you would follow similar steps to graph and calculate with data. However, the specific steps you would follow would be different. Consult your user’s manual for the software you use.
