What do the colors on the V-I filter mean?
Posted: Sat Nov 12, 2016 5:21 am
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
