\subsubsection{Principal Component Analysis}  We present the velocity channel covariance matrices of runs W1T2t0.2 and W2T2t0 in Figure 3. Multiple covariances of velocity channels between -2 and 2 km/s are larger in run W1T2t0.2 than those in run W2T2t0. There appears to be distinct peaks at the center of both matrices. We find that feedback augments and further separates these peak. peaks.  This corresponds to the typical expansion rate of the wind shells. (This appears to, so far, be the only statistic that I don't give much background on. I feel as if the PCA is more about obtaining the eigenbasis for the covariance matrix than it is about the actual covariance matrix. Here, we only look at the covariance matrix. The distance metrics table uses the eigenvalues, so I'm thinking of mentioning some of the PCA background there. I just find it kind of ironic that on this section appears to have one of the most interesting changes while being one of the shortest sections)
