Leading PCA components v^k (left) and their respective frequency amplitudes a^k (right) for Field 2 as observed by feed 6 prior to the map-PCA filter; this feed is the most sensitive to pointing-correlated systematics. All maps are divided by their respective uncertainties to highlight the key morphology. All rows share the same color range and y-axis scale, but the specific values have been omitted as they are not easily interpretable.
