Caption: Figure 8.

Cumulative error in image reconstructions with respect to the pixel flux of the original channel maps. The top and middle panels correspond to the errors in the G34.30 and LkCa 15 reconstructions using PCA and NMF (Figures 4 and 5). The bottom panel shows the cumulative error from the select channels of each sampled source in Figure 6 using NMF.
