Pointing model failure

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:

1. Pointing models are incorrect
2. Pointing model signs have been misinterpreted (don't think this one is possible based on other graphs)
3. Uhh... ideas?

Next step, I'll use the individual maps with no ptg mdl and find out what the offsets should be....
