Hi all,

I'm analyzing some motion data and I had a two quick questions about the last two columns of the fmc.mcdat file. According to the wiki, the 9th column is RMS error after correction. Could someone shed some light on what RMS stands for and how it's useful? Also, the 10th column is the total vector motion in mm...is this total before or after motion correction?

Thanks in advance!
