Some sample plots of flux-vs-iteration number in the Galactic Center. The above is for a 13-pca-component map, and the plot is of the northeast peak of SGR B2. The other plots (available in postscript below) are of two other points in the GC, and the last one is of the whole of SGR B2 (it's a very large aperture). ps version here: http://sites.google.com/site/bolocam/pipeline/mapping/iteratetoconvergence.ps?attredirects=0 or /scratch/adam_work/plots/iteratetoconvergence.ps
