Same as Figure 7, but for NRS1. While the ICA eigenvectors are able to successfully remove the linear trend seen in NRS1, nearly every eigenvector showed some residual signal around the transit. This made it challenging to remove the instrumental systematics through this technique without affecting the transit depth, as highlighted here. The eigenvectors for the PCA behaved similarly.
