<p>I attempted to map L111, L033, and W3/4/5 with the pointing model
corrections applied. That was a failure. Two images are attached to
illustrate the problem - relative pointing is clearly not correct
(middle of L33, bottom left of L111).
So.... possibilities:</p>
<ol class="arabic simple">
<li>Pointing models are incorrect</li>
<li>Pointing model signs have been misinterpreted (don't think this one
is possible based on other graphs)</li>
<li>Uhh... ideas?</li>
</ol>
<p>Next step, I'll use the individual maps with no ptg mdl and find out
what the offsets should be....</p>
