inteprating excel data

[axl3]

hi all,

i have recently collected some data on rigid body and i have uploaded it onto microsoft excel. Howvere i am stumped when it comes to deciphering the data collected especially since the data headings are lined in a linear fashion while the data collected are arranged in a parallel sequence. i am also trying to make sense of qx, qy, qz and qw and what these values meant. Any help will be greatly appreciated. thank you

The format is listed at the top of the CSV file in the 'comments' section. In addition to the quaternions standard yaw, pitch, and roll values are in the CSV as well.

When I defined a rigid body, say, with 3 markers and perform some capture, I will have data on the x, y, z etc of the rigid body per frame.
(1) Which part of this rigid body does this data refer to?
(2) Does setting origin on one of the markers make a difference in the interpretation of the data?
