[PINPOINT-859]  Reject (false) solutions with vastly differing plate scale
Type Enhancement

Severity Closed
Resolution Complete

Description 
Besides increasing the number of stars matched required for a solution, check the plate scales against those set. Do not look at PA as one of PinPoint's major features is the rotation free solution.

  Change preposterous plate scale test to apply after iteration, not during!

Ken Pendlebury found a regression! I was testing the plate scale within the WCS refinement loop, and there is can vary around as the WCS and the distortion is iterated. I had to relax the test within the loop and apply the tighter test after that process completes!

  Final touches on false solution resistance and docs.

Narrow it again! Now 75% to 125%. Regression tests show that this wikll virtually eliminate falsies. The PSF + RemoveHotPix version of Test1 was producing ome false solutions, they are gone.

Cut the tolerance to 0.5 to 2 from 0.25 to 4. Changed the plate scale error message to be a hint.

Accumulating time under the "too many false solutions" ticket.

Doing it in field_compare.cpp was a total loser. I left the code there, but commented out. See those comments.

What I would LIKE to do is for this test to be included in the initial search for a solution, as the last criterion (after all of the other possible rejections for a solution).

Ha ha, this logic is already in the engine, but the limits may be WAY too wide!
