    <p>Since my gigantic mapping run is still going, I'm going to work
primarily on developing code for testing the maps, and determining
important information about the mapper.
The data paper will require an iteration-to-convergence figure, or at
least an estimate of degree of convergence.</p>
<ol class="arabic simple">
<li>Need to develop code to show iteration-to-convergence<ol class="arabic">
<li>need it for both NxNpca and ascending/descending</li>
<li>have to use region files? make some sort of region reader?</li>
<li>pick demonstration sources</li>
</ol>
</li>
<li>Compare N<sub>pca</sub> results for bright, faint sources</li>
<li>Compare iterating with/without deconvolution</li>
<li>Compare median/average/baseline sky subtraction</li>
<li>Analyze efficiency...</li>
<li>Try to figure out what's causing huge offsets. Is it Galactic
Coordinate mapping?</li>
