What do the colors on the V-I filter mean?

Hi!

My name is Grace and I am in 8th grade. I am doing The Milky Way and Beyond: Globular Clusters for my science fair experiment. In the experiment, I need to take the V-I color data from the Milky Way and M87 galaxies and graph it; therefore, I also need to make inferences on the data. However, I did a boatload of research and could not find out what the numbers mean. I could only find information on what the B-V data means, but not the V-I. Are they the same thing? Or is there a difference? What number corresponds with each color?

Hope you can help,
Grace

Hi Grace,
Sorry for the late answer. Please take a look at the following URL for the terms that you had mentioned and the meaning of each: https://en.wikipedia.org/wiki/Photometric_system

Please let us know if there's anything else we can do to help.
