I am reading this article about measuring similarity between x-rays and DRR's (2d projections from CT) and the article speaks about different measurement techniques accuracy vs. attraction range.

I can't find any information online on what "attraction range" means. Can someone point me in the right direction?

From the context of the usage it seems to be a measure of standard deviation. Is this correct?

It seems to me that attraction range means the area which is searched for an optimal solution, so that a wider range of search is more robust and a smaller range is riskier. I'd appreciate confirmation of my understanding.
