A demonstration that the spatial transfer function can be improved to ~80% at ~300 arcseconds by reducing the number of PCA components subtracted. However, image fidelity and noise backgrounds suffer, so these sorts of maps are probably less ideal for point source extraction. Below:

0 PCA
3 PCA
10 PCA
15 PCA
