Reconstructions, residuals, and residual errors with respect to ground-truth images of select channels of G34.30 and LkCa 15 using NMF. The residual images were generated by taking the difference of the ground-truth image and corresponding reconstruction. The residual error for channels 320 and 2966 in G34.30 is 10% of the maximum signal intensity, and 40% for channel 3547. The residual error of both channels in LkCa 15 is 30% of the maximum signal intensity.
