  1. The observations are unitless, since they have been scaled by the maximum observation (scaling factor). There were a total of twelve different scaling factors, since our dataset was a combination of twelve different observation datasets viz. two CAMs, three process cells and \(\alpha\) & \(\beta\) observations
